Foods

sera marin Gourmet Nori is the delicacy consisting of 100% gently dried Nori algae for aquarium animals such as algae eating fish, crustaceans and sea urchins.

The natural marine macro algae from unpolluted waters are an attractive, easily digestible snack. Their high percentage of omega fatty acids, vitamins, minerals and trace elements such as iodine makes them particularly valuable.

The delicacy is also very popular among many animals in fresh water. However, in the latter case they should be fed sparingly due to their relatively high iodine contents.

Feeding recommendation

Feed small amounts in-between meals daily. Only as much as the animals take up within a short time. Use only sparingly in freshwater due to the high iodine amounts.

Masstick’s legacy.

DKI marine is a balanced food, which has been developed to satisfy the nutritional needs of omnivorous marine fish from the coral reef biotope.

DKI marine marine comes in the form of tender granules and neutral buoyancy. It is available in grain sizes of Ø 0.8 mm, Ø 1.2 mm and Ø 2 mm.

DKI marine main ingredient is freeze-dried shrimp (Palaemonetes varians) coming from our Veta de la Palma fisheries located in the Doñana Natural Space.

The microalgae (Nannochloropsis, Tetraselmis, Isochrysis, and Phaeodactylum) included in its formula provide fatty acids, completely natural vitamins, functional compounds and bioactive ingredients which preserve and boost the marine fishes’ immune system and general health.

Thanks to its essential amino-acid contents, its fatty acid contents, and its fully bio-available micronutrients, which are all involved in the fishes’ metabolic pathways, the product’s morphological and organoleptic characteristics, together with its highly valuable biological proteins, means that the DKI marine granules are a food system based on a holistic concept of nutrition for coral reef marine fish.

Shrimp food with spirulina and alder cones

Sera Shrimps Nature is the staple food consisting of gently manufactured granules without dyes and preservatives for all shrimps in fresh and marine water.

The balanced composition with ingredients close to nature, such as spirulina and alder cones, provides everything the shrimps require for healthy growth and safe molting. Fertility, splendid coloration and disease resistance are enhanced in a directed way.

The sinking small granules keep their shape for a very long time, thus allowing the shrimps – according to their natural feeding habits – to grab them and slowly graze them off without polluting the water.

Stick-on Tabs for bigger marine fish

sera marin Spirulina Grazer XL is the herbal food for mainly herbivorous fish, such as tangs, angels and wrasses. The carefully manufactured tablets sink to the bottom or can be attached to the aquarium glass by slight finger pressure. This allows for watching even shy fish eat right in front of you. The particularly high amount of spirulina algae (21%) supports healthy digestion and liveliness. The balanced food supports healthy development, splendid appearance as well as the natural behavior of the animals.

Brine Shrimp Eggs

Artemia is a genus of aquatic crustaceans also known as brine shrimp. It is considered by the aquarium industry as the single most important food item in the world simply due to the high levels of nutrition in brine shrimp. Brine shrimp can be quickly & easily hatched and grown at home with brine shrimp eggs (Artemia Cyst).

Directions:

Hatching: Environment Conditions

• Salinity:
• When preparing your hatching solution, 25 parts per thousand (ppt) salt solution is ideal under most conditions. This equates to around 1.018 specific gravity as measured with a hydrometer. If you lack a hydrometer, this salinity can be achieved by dissolving approximately 1 and 2/3 tablespoons of salt in one quart (roughly, one litre) of water. Be sure to use non-iodized salt.
• pH:
• Proper pH can be important in hatching brine shrimp. A starting pH of 8.0 or higher is recommended. In areas where the water pH is below 7, Epson salt or magnesium sulphate can be added at the rate of 1/2 teaspoon per quart of hatching solution.
• Temperature:
• Optimum water temperature for a 24-hour complete hatch is 80-82°F (26-28°C). Lower temperatures will result in a longer hatching time and inefficient hatches. Do not exceed 86° (30°C). Do not place an immersion heater directly into your hatching container! An immersion bath is a preferred method to maintain constant hatching temperatures. Alternatively, an incandescent bulb placed above the hatching cone can provide sufficient heat in the right environment.
• Light:
• Illumination is necessary to trigger the hatching mechanism within the embryo during the first few hours of incubation. Maintaining a light source during the entire incubation period is recommended to obtain optimum hatch results and, as mentioned above, for temperature control.
• Aeration:
• Constant aeration is necessary to keep cysts in suspension and to provide sufficient oxygen levels for the cysts to hatch. A minimum of 3 parts per million dissolved oxygen during the incubation is recommended. Strong aeration should not damage or hurt the brine shrimp cysts or nauplii. A [rigid air tube] is ideal to direct air to the bottom of the cone and to prevent unhatched eggs from settling. We do not recommend an airstone.
• Stocking Density:
• 1 gram per litre or quart or approximately 1/2 level teaspoon of cysts per quart (or litre) is recommended for optimum hatching percentages. A higher stocking density will result in a lower hatch percentage and difficulty separating hatched nauplii from unhatched egg and shell.
• Hatching Cone:
• Flat-bottom hatching vessels should be avoided. Cone or "V" bottomed containers are best to ensure that the cysts remain in suspension during hatching. Be sure to thoroughly wash the hatching cone with a light chlorine solution, rinse, and allow to air-dry between uses. Avoid soap. Soap will leave a slight residue which will foam from aeration during hatching and leave cysts stranded above the water level.
• Incubation Period:
• Generally, the optimum incubation time is 24 hours. Egg which has been properly stored for more than 2-3 months may require additional incubation time — up to 30-36 hours. Oftentimes, eggs will hatch in as few as 18 hours. If a smaller size nauplii (Instar I) is desired, a harvest time of 18 hours is recommended after which Instar I (first stage) nauplii can be collected before metamorphosis into Instar II.

Helpful Hint:

Brine shrimp egg is sometimes very buoyant. To maximize the hatching percentage, it is sometimes helpful to swirl the water inside the hatching container with your finger once or twice at intervals in the first 4 to 6 hours of incubation to knock down eggs that have been stranded on the side of the container above the water-line. After about 6 hours, the eggs are usually well-hydrated and will stay in the water column.

Hatching Procedure

The following steps will achieve optimum brine shrimp hatch rates.

• Set-Up:
• Place hatching cone or similarly shaped vessel in a well-lit area. Cone should be semi-translucent for ease of harvesting and light transmission.
• Add Water:
• Fill the cone with water and adjust the salinity to 25 ppt (parts per thousand). Optimum hatching temperature is 82°F (28°C).
• Add Cysts:
• Add cysts at the rate of 1 gram per litre.
• Aerate:
• Provide adequate aeration to keep cysts in suspension.
• Hatch:
• Depending upon water temperature, cysts should hatch in approximately 18-36 hours.
• Harvest:
• After hatching brine shrimp, turn off or remove aeration and wait several minutes for the shells and baby brine shrimp (or nauplii) to separate. Newly hatched nauplii will settle to the bottom of the cone or move towards a light source; the shells will float to the surface. Once separated, the nauplii can be siphoned from the bottom with a length of air tubing or gently drained through the bottom of the cone through a valve, if so equipped.
• Rinse:
• The warm incubation temperatures and metabolites from the hatching medium create ideal conditions for a bacteria bloom. Rinsing of the baby brine shrimp in a fine mesh net or sieve using clean fresh or saltwater is important before feeding them to your fish.
• Clean Equipment:
• Tanks and brine shrimp hatching equipment should be cleaned and disinfected routinely.

Incubation Period:

• Generally, the optimum incubation time is 24 hours. Egg which has been properly stored for more than 2-3 months may require additional incubation time — up to 30-36 hours. Oftentimes, eggs will hatch in as few as 18 hours. If a smaller size nauplii (Instar I) is desired, a harvest time of 18 hours is recommended after which Instar I (first stage) nauplii can be collected before metamorphosis into Instar II.

Harvesting or collecting brine shrimp

• Harvesting newly hatched nauplii requires some patience and the method used depends upon your equipment and your needs. When collecting from an Imhoff cone or inverted soda bottle, one method is to remove the airline and allow the nauplii to settle to the bottom of the cone. This will take several minutes. As the nauplii accumulate at the apex of the cone, use the airline with rigid tubing attached to siphon the nauplii into a collection dish filled with fresh water. Do not allow the nauplii to become tightly packed at the bottom of the cone and risk suffocation. After siphoning, wait several minutes and repeat. Take care to avoid siphoning the unhatched eggs that normally settle first. If you have difficulty siphoning the newly hatched nauplii without siphoning unhatched eggs or shell, we suggest that you finish siphoning the majority of nauplii into the holding dish, rinse out the cone and then pour the dish containing nauplii and water back into the cone, add clean water to the cone and repeat the siphoning process as the nauplii again settle to the apex of the cone. It is a good practice to pass the nauplii and water through a small mesh to minimize the introduction of the hatching water into the aquarium.

Polyp Feast Pro-Biotic

A concentrated blend of specially selected aquacultured marine plankton strains & bacteria strains to naturally reduce nutrients caused by feeding. Polyp Feast contains particles of various sizes, feeding all corals with a high protein diet for accelerated growth and better colouration while keeping nutrients down.

Storage

Replace twist cap after every use and store in a cool dry place

Directions:

For lightly stocked tanks, mix 1/4 of a teaspoon (0.5g) for every 100L of the tanks total volume with RO or tank water. Heavily stocked tanks mix 1/2 of a teaspoon (1g) for every 100L of the tanks total volume with RO or tank water. Target feeding is recommended with pumps and wavemakers turned down or off. Broadcast feeding is another method.

Composition: Rich in essential EPA, ARA, DHA polyunsaturated fatty acids. The Easy Reefs® microalgae species used are Nannochloropsis (50%) and Isochrysis (T-ISO) 50%.

Presentation:
Easyrich is available in 14 and 28 single-use packets and Easyrich PROF 250 ml format.

Directions for use:
To enrich rotifers and copepods:
Disperse 1.5 ml of Easyrich in 50 ml of water and add it to 500 ml of “culture”, two hours before using it to feed adult organisms.

To enrich saltwater artemia:
Disperse 1.5 ml of Easyrich in 250 ml of water of the same salinity as the culture and add the harvested artemia 2 – 4 hours before using it to feed adult organisms.

Food needed: 
Easy Reefs EasyRoti or  Nannochloropsis (80%) +Tetraselmis (20%)

Culture cycle from strain: 5 days

Recommended sea water density: 1019, although they can be cultured well up to 1022.

Culture temperature: 22ºC to 28ºC. Optimum culture temperature: 24ºC.

To filter the rotifer you should use a 50 micron net.

Once you start the culture you will be able to harvest rotifers after 6 days. You will have one flask for the “strain” and another one for the “production” culture.

The information that follows describes the dosage to be used in ideal conditions assuming that the rotifer density is the ideal. Sometimes it is possible that the amounts of microalgae that are being added do not adjust to the rotifer demand. This is because in aquariums people don’t count rotifers, so the amount of microalgae added is not exact to the amount of rotifer. If the culture water gets clear this would mean that the amount of microalgae wasn’t enough. If rotifer remains with no food for more than 4 hours, the number of eggs will decrease and so will the population growing yield. It is essential that the rotifer always have food.

Rotifers are very sensitive to changes of water parameters. Rotifer population would be affected if the water quality decreases. If you observe an excess of dirtiness in the cylinder then you should filter the rotifer and start the culture in a new clean flask and add the amount of microalgae needed.

Depending on the intensity of the green colour that the flask has, this will indicate the amount of microalgae needed. With time and experience, the difference in green colour will let us do our own feeding protocols. There is no difference in using live or Easyroti as food. 

We will put a glass tube with a gentle air bubbling (5-10 bubbles per second) in the graduated flask used for the rotifer culture. This air bubbling will provide a homogeneous mixture in the culture. An excessive water movement will make rotifers to loose their eggs and this way they won’t hatch.

 It is recommended to feed twice a day. But due to the lack of time, rotifers are usually fed once a day.

DAY 1
Initial conditions: “Strain” culture with  500 mL of sea water, number of rotifers 400 rot./mL to 600 rot./mL and 4 ml of Easyroti Nannochloropsis (80%) +Tetraselmis (20%).

Final conditions: The culture will end up with a volume of 1L with microalgae.

Instructions: Resuspend 4ml of Easyroti in 0.5 L of sea water. Add the rotifer inoculums and add sea water until the total volume is 1 Litre.

DAY 2
Initial conditions: 1 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 500 rot/mL

Final conditions: The culture will end up with a volume of 1.4 L with microalgae.
Instructions: Resuspend 4 ml of Easyroti in 0.5 L of sea water  and add 0.4 L to the rotifer culture.

DAY 3
Initial conditions: 1.4 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 500-600 rot/mL

Final conditions: The culture will end up with a volume of 1.8 L with microalgae.
Instructions: Resuspend 8 ml of Easyroti in 0.5 L of sea water and add 0.4 L to the rotifer culture.

DAY 4
Initial conditions: 1.8 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number:  600 rot/mL

Final conditions: The culture will end up with a volume of 2 L with microalgae.
Instructions: Resuspend 6 ml Easyroti in 0.25 L of sea water and add 0.2 L to the rotifer culture.

DAY 5
Initial conditions:  2 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 700-800 rot/mL

From this “strain” culture we will get a volume of 0.5 L to start a new “strain” culture in another 2 L flask and start a new culture cycle from day 1.

We will add Easyroti to the old “strain” culture, from now on “production” culture, until it reaches 2 L. If the cylinder is very dirty then we will pour the culture to a clean flask and carry on with the production culture.

Instructions:  To the “production” culture we will add 8 ml of Easyroti in 0.5 L of sea water. For the “strain” culture start a new cycle from day 1.

DAY 6
Initial conditions: “Strain” culture the same as day 2. “Production” culture 2 L with 800 rot/mL, it will be nearly clear and with no microalgae.

The “production” culture would be used to harvest 0.5 L every day and be used as food for the aquarium (If you don’t feed the aquarium you must do the harvest anyway so you can feed the rotifer with microalgae). If you harvest 0.5 L of rotifer you always have to add 0.5 L of sea water with 8 ml of Easyroti .

The “production” culture will be kept until the flask is dirty (5-7 days).

When the “strain” culture reaches day 5 of culture it will be converted to the “production” culture and a new “strain” culture will be created, the same way as it has been explained on day 5.

Composition: easy reefs® Tetraselmis (100%) microalgae species.

Dosage: The dosage depends on the density of the artemia we are feeding. The consumption is 4 ml of Easyart per 10 litres of culture per day for the first 5 days, (nauplius and metanauplius) and 8 ml of Easyart per 10 litres of culture per day from day 5 of culture (juvenile artemia and adult). If the water of the artemia culture goes clear a few hours after adding Easyart (microalgae have been ingested), then more Easyart must be added.

Example for artemia culture in 10 litres:
1. Hatch the artemia cysts following the manufacturer directions.

2. Once they have hatched, wait 6 hours and start feeding with Easyart.

3. Put 0.5 litres of seawater in a glass blender.

4.-Add 4 ml of Easyart and disperse the microalgae by shaking.

5. Remove 0.5 L of water from the culture so the next algae batch can be prepared.

6. Slowly add the microalgae to the tank to avoid sediment suspensiono.

EasySPS EVO is a premium mixture of natural marine plankton in a mineral suspension that has been specifically designed to be used with a dosing pump to ensure an accurate and regular nutrition of the SPS corals. EasySPS EVO contains particles ranging from 0.2 – 400 microns (55% from 0,4 to 200 microns) making it ideal to facilitate the capture by the Small Polyp Stoney Corals (SPS) which spend energy for respiration, mucus production, growth and reproduction.

Research has shown that the total energy demand cannot be met by photosynthesis alone. With the use of highly efficient protein skimming and fine mechanical filtration we eradicate almost all organic molecules and particulate matter from our systems resulting low levels of organic nourishment available to our SPS corals. Corals cannot survive exclusively from zooxanthella alone as they require extra sources of proteins, nutrition and carbohydrates.

EasySPS EVO supplies complex carbohydrates, natural lipids and nutritional proteins which provide an immediate source of energy for cellular respiration as well an important energy source beneficial for growth, color and most importantly survival. Useful in recreating the water conditions in and around natural coral reefs, used in conjunction with EasyBooster will help to significantly reduce the need of live food inside SPS dominated aquariums. In this way, both zooxanthella and EasySPS EVO are able to cover all nutritional requirements in the correct proportion.

• EasySPS EVO is composed of Palaemonetes varians, Tetraselmis, Isochrysis, and Phaeodactylum.
• The composition of EasySPS EVO boosts corals with high nutritional value proteins with a balanced aminogram, lipid profile rich in EPA, ARA and DHA, carbohydrates and functional micronutrients involved in the metabolic system of these animals.
• All ingredients are produced at the EasyReefs facilities. They produce their own raw materials to ensure high quality standards in every production process. EasySPS EVO will enhance the brightness and intensity of the colors of your corals. It will also help strengthening and growing SPS corals. EasySPS EVO contains particles ranging from 0.2 – 400 microns (55% from 0,4 to 200 microns) making it ideal to facilitate the capture by the SPS polyps.

HOW TO USE

EasySPS EVO Initial dose: 1 ml per day for every 250 L of tank water. Then, increase the dose 25% weekly until you reach the recommended dose.

Daily recommended dose: 4 ml per day for every 250 L of tank water.

Recommended to use: It is best to feed EasySPS EVO to the aquarium using a dosing pump to ensure the regularity and accuracy of the doses. Apply the product near an internal circulation pump to ensure the total dispersion of the product.

Features:

For all living organisms, stress represents a major concern when dealing with the maintenance of an appropriate physiological status. In a wide sense, the discomfort associated to stress, either physical or environmental, can trigger in individuals a series of known physiological short and long-term responses in order to face and adapt to impose changes. Particularly, aquarium fish are subject to a broad variety of different stressors because their homeostatic mechanisms strongly depend on prevailing conditions in their immediate surroundings1. There is a well-known set of aquarium fish-specific stressors, the most relevant being: i) improper water parameters (ammonia, nitrate, pH, temperature, salinity, oxygen…), ii) inadequate tank size, iii) lack of hiding places, iv) overstocking of tank, v) harassment from other fish, vi) infections with pathogens that cross-react with different host species of different geographical origins, vii) contaminants (chemicals, medication), and vii) malnutrition of captive fish because of suboptimal feed formulation, as the precise nutritional requirements for aquarium fish species is not well-determined.

Physiological responses to stress include changes in heart rate, blood pressure, blood sugar, and release of adrenergic (such as adrenaline) and glucocorticoid hormones such as cortisol, which is considered a hallmark of the stress response. Although activities of these hormones are beneficial to tackle short and sudden stressors, negative health effects will be elicited when hormonal stress responses persist and become chronic, including depletion of energy reserves, muscle breakdown, interference with osmoregulatory processes, and immune suppression2. Thus, the lowered immune response will eventually allow parasites, bacteria, and fungi to infect a stressed fish and cause disease and death.

In this scenario, dietary supplements that contribute to enhance fish resistance against infection diseases and/or to act as immunostimulants in order to improve immune status of aquarium cultured fish are currently of major concern in these ecosystems.

TECNICAL INFORMATION
Easysps is a phytoplankton and zooplankton blend. It is formulated to meet specific nutritional requirements of corals, such as SPS (Short Polyp Stony corals) and non-photosynthetic corals like gorgonian.

COMPOSITION:
Palaemonetes varians: Natural zooplankton as source of high nutritional protein and essential amino acids. Rich in glutamine that triggers a quick response from corals.
Tetraselmis chuii: Source of natural antioxidants, Vitamin C, E, B12, Superoxide Dismutase, high digestibility and rich in EPA and ARA essential fatty acids.
Phaeodactylum tricornutum: Stimulates the immune system, rich in 1-3, Beta glucans. High content in EPA essential fatty acid.
Isochrysis galbana (T-ISO): Very rich in DHA essential fatty acid and micronutrients involved in complex metabolic processes.
Sardine oil: Texturing activity smoothens easysps particles.
Tocopherols: Based on natural extracts of Rosmarinus officinalis, antioxidant that stabilizes essential fatty acids.

PRODUCTION:
We have reached the perfect conservation of all components present in this formulation thanks to the manufacturing process including freeze drying (lyophilization) and cold extrusion.
With our fresh ingredients, lyophilization process takes place first, agglomeration by cold extrusion as a second step and ulterior milling process without compression.
This will give out the following particle size ranges:

0,4 – 200 µm – 54.90 % of total particles
200 – 400 µm – 28.30 % of total particles
400 – 1000 µm – 16.70 % of total particles

– Proteins >50%: High content in protein but moreover, it contains all essential amino acids, all amino acids and its proportional natural content.
  All key elements for correct growth and development are present in this feed.
– Fats 6%: Equilibrated EPA/ARA/DHA content. These essential fatty acids are not added but naturally present in the microalgae of the formula, 
  Phaeodactylum tricornutum, Isochrysis galbana (T. Iso) and Tetraselmis chuii.
– Carbohydrates 18%.

HOW DOES IT WORK?
The composition is very close to natural coral tissue (Approximately 50% proteins, 30% lipids and 20% carbohydrates). Easysps contains 53% proteins,
6% lipids and 20% carbohydrates.
Coral tissue has a higher amount of lipid content. The difference has a good explanation for our easysps,
photosynthetic SPS corals are animals that live in symbiosis with vegetal cells (Zooxanthella) from which they can obtain these lipids.
The zooxanthella produces most of the nutrients for their own development and survival, they only assign a small fraction to corals
(80% lipids, some sugars and small quantities of proteins as glutamine and alanine that are not sufficient as protein source).
In other words, corals cannot survive exclusively from zooxanthella and they need extra sources of proteins, nutrition and carbohydrates.
Corals get it from zooplankton, phytoplankton, bacterioplankton and also from free amino acids dissolved in water.
The nutritional composition of easysps boosts corals with high nutritional proteins, natural lipid profile rich in EPA, ARA and DHA,
carbohydrates and functional micronutrients involved in the metabolic system of these animals.
In this way, both zooxanthella and easysps are able to cover all nutritional requirements in the correct proportion.

RESULTS:
By the increase of the metabolic rates in corals due to the increase of nutrient availability in the water, we will get many positive results:
1. Coral growth will increase. Keep an eye on the calcium concentration, carbonates (kh) and magnesium, they will be consumed by corals due to rapid growth.
We recommend water test during the first few weeks while using the product.
2. Inorganic nutrient consumption will increase. Nitrates and phosphates will decrease because corals will metabolize part of them.
3. Coral color improvement. Based on observations, corals may increase the internal peroxidation during digestion when there is heterotrophic feeding.
This increase of peroxidation’s will reach antibacterial capabilities. The high sensitivity of zooxanthella (dinoflagellates) to oxidative processes may explain
zooxanthella concentration decrease in coral tissue and color enhancement. The bioavailability of essential amino acids and presence of essential fatty acids will
contribute as precursors for pigment production (fluorescent and non-fluorescent pigments). Amino acids can be used similar to mycosporin with a similar mode of action
against UV-A radiation, Easysps is the perfect solution for this purpose.

DOSING:

Initial dosing:
Add 1 level scoop per day with the dosing spoon for every 250 L of water.
Adjusting the dose: Dosing may be increased as a reaction of the coral response, benthic fauna and aquarium filtration capacity.
The presence of residual nutrients, non-desired algae growth, may indicate an overdosing of easysps.

How to dose:
Add the desired amount of easysps inside the vial tube.
Fill half the tube with water, osmosis water is preferred, close the cup and shake it for mixing. Foaming is normal during this process.
Let it stay for 1 minute for total product hydration.
Add the content in the aquarium near a strong water flow or circulation.
During the first weeks, add the easysps after lights switched off. After a few weeks, it may be added at any time of the day.

Attention:
A simultaneous use of easybooster and easysps is highly recommended to prevent possible nutrient limitations and support the natural balance of the system.

Masstick is a blend of diverse, all natural, self-production, highly technical compounds, providing natural and balanced nutrition for omnivorous fish and marine invertebrates.

Masstick is comprised of raw materials of marine origin. It does not contain attractants, artificial preservatives or synthesis products.

Masstick is a self-adhesive paste in a powder formula, ready for rehydration with water.

Once it is rehydrated, it can be stuck to any surface of the aquarium, depending on the animals’ needs.

The rehydratable powder formula allows Masstick to be blended with any mollusc or crustacean pulp as well as eggs from fish, molluscs and crustaceans, artemia, mysids, copepods, rotifers and medicines that are administered orally.

Once prepared and introduced into the aquarium, Masstick does not disperse into the water for hours, so it can be completely taken advantage of by fish and crustaceans. This feature allows the product to be used as “ad libitum” or rationed feeding.

Because Masstick is comprised mainly of freeze-dried crustaceans, it does not contain fish skeletons and is thus very low in phosphates compared to its protein content.

Instructions

Add Masstick to osmosis water in a 1 to 0.5 ratio.

Example: Mix 14 g. of Masstick with 7 ml. of osmosis water. Knead in a small ziplock bag until a homogenous mixture is obtained.

Once the mixture is homogenous, Masstick may be used immediately or frozen for later use. If freezing Masstick, it should be used within five weeks after preparation.

Instructions for use:
Take a portion of Masstick and stick it on a rock, a branched coral skeleton, or the aquarium glass (preferably on the lower third), or depending on the food-obtaining habits of the animals in the aquarium.
