PRO-REEF Meersalz / Sea Salt
Regular price $159.99 Sale price $149.99 Save $10.00Features:
The pharmaceutical grade sea salt especially for modern reef aquaria.
Tropic Marin® PRO-REEF Sea Salt has been designed to meet the special requirements of reef aquariums with optimized concentrations of calcium and magnesium, which promote the growth of corals. The lower buffering and the correct pH value serve to stabilize the natural water values, and particularly, the hardness of carbonates, even with the use of calcium reactors. Natural and stable conditions for delicate marine life are achieved only by accurately balancing all influencing factors.
Tropic Marin® PRO-REEF is thus the ideal foundation for the care and growth of fish, corals and other aquatic invertebrates in modern reef aquariums. Use seawater prepared with Tropic Marin® PRO-REEF for regular water changes in your seawater aquarium, to start a new aquarium and to re-equilibrate the pH of a tank.
Benefits:
Optimizes calcium- and magnesium concentrations as well as alkalinity and pH.
Designed to meet the special requirements of modern reef aquaria with higher calcium requirements.
Especially designed for use with calcium reactors or mineral additives.
To maintain the alkalinity in a 7-8° dKH range.
Manufactured from pure, pharmaceutical grade salts.
Contains all major- and minor elements in the exact proportions found in tropical sea water.
The 70 trace elements are completely soluble due to the use of the mixed-crystal method.
Compliance with the most stringent quality control measures for the production of pharmaceuticals ensures nature-identical seawater.
Free from nitrates, phosphates and other unwanted chemicals.
How to use:
To achieve a salinity level of 32-35 ‰ (psu), dissolve 35 ml of Tropic Marin® PRO-REEF per liter or approximately ½ cup of Tropic Marin® PRO-REEF per US gallon water. Dissolve almost all of the salt in a clean container already filled with the full volume of RO/DI water at a temperature of 73-77°F / 23-25°C while circulating/stirring the water. Do not concentrate the mixture by adding the full amount of salt to a smaller amount of water.
Note: Always add the salt to the water, never the water to the salt. Making a concentrated mixture will cause a calcium carbonate precipitate to form.
When you have added ALMOST all of the salt and the mixture is fully dissolved and clear, start measuring the specific gravity with a hydrometer or similar instrument. Keep adding small amounts of salt until the specific gravity is the value you desire. The specific gravity of the sea salt solution should range from 1.025 to 1.027 (at 73-77°F / 23-25°C) and the pH-value should be in the range of 8.0 – 8.4. If all parameters are correct, the salt water is ready to use.
After setting up a new aquarium it takes a few weeks of water being circulated and correct lighting conditions to achieve the biologically stable environment required for the care and breeding of delicate marine organisms.
A weekly, partial water change, replacing 10 % of the total water volume with Tropic Marin® PRO-REEF, will help to maintain the water quality that your livestock needs for good health.
Parameters: approx. 7° KH, calcium approx. 440 ppm, magnesium approx. 1350 ppm
Application: For reef tanks with higher calcium requirements. To maintain the alkalinity in a 7-8° dKH range; particularly suitable when using a calcium reactor.
Use the new dosing calculator for an easy determination of the required amount of salt for your aquarium.

Syn-Biotic Meersalz / Sea Salt
Regular price $89.99Features:
Pharmaceutically pure sea salt with probiotic bacteria and prebiotic bacteria food
The new Tropic Marin® Syn-Biotic Sea Salt contains probiotic bacteria for fish and shrimp and special prebiotic bacteria food to promote probiotic bacterial growth and to create low-nutrient conditions in the aquarium for LPS and SPS corals. The term synbiotic refers to supplements which combine probiotics and prebiotics in a form of synergism.]
Tropic Marin® Syn-Biotic Sea Salt is ideal when you are setting up a new tank and every time you expand the tank’s stock. It has been proven that probiotic bacteria help to overcome stress and disease while enhancing the health and well-being of fish and crustaceans. For the best results, the aquarium should have a water change with Syn-Biotic Sea Salt prior to any new stock being introduced.
The contained prebiotic additives promote the integration of nitrates and phosphates in bacterial mass for low-nutrient conditions and the vivid colours of LPS and SPS corals. For a sustained acclimatization of animals to the aquarium conditions and to stabilize the microbiology of the tank system we recommend using Syn-Biotic Sea Salt permanently. Each water change with Syn-Biotic Sea Salt automatically adds the probiotic bacteria necessary to maintain healthy biological processes.
Benefits:
It has been proven that probiotic bacteria improve the health and well-being of fish and crustaceans and assist them in overcoming stressful situations and illness
Prebiotic additives promote the integration of nitrates and phosphates in bacterial mass for low-nutrient conditions and the vivid colours of LPS and SPS corals
Contains additional nitrifying and de-nitrifying bacteria to support the nitrogen cycle
To maintain the alkalinity in a 8-9 °dH range.
Ideal for a new tank installation, a new stocking process and for every livestock increase
Suitable for permanent use – for a stable microbiology within the aquarium
Dissolves in water quickly and completely
Produced with pharmaceutically pure salts, without any nitrate or phosphate additives or other unnatural enrichments
Universally applicable – suitable for keeping and breeding fish, corals and other invertebrates, as well as seaweed
How to use:
To achieve a salinity level of 32 – 35 ‰ (psu), dissolve 35 ml (approx. 37-40 g/1.3-1.4 oz.) of Tropic Marin® Syn-Biotic for every litre or one half cup for every US-gallon of water in a container, stirring continuously. The specific gravity of the sea salt solution should be 1.025 to 1.027 at a temperature of 25 °C/77 °F. The prepared saltwater can be used as soon as the salt is fully dissolved.
Note: Always add the sea salt to the water – not the other way round. When checking the conductivity of freshly prepared Syn-Biotic saltwater the conductometer will show ca. 10 % low results, because the contained organic substances affect the measurement. We recommend measuring the specific gravity with the Tropic Marin® Hydrometer.
It is normal for the salt water to turn slightly cloudy and this indicates that the synbiotic additives are taking effect. After setting up a new aquarium it takes a few weeks of circulating and lighting to establish stable biological conditions for the care of delicate marine organisms. Changing up to 10 % of the water every week using Tropic Marin® Syn-Biotic helps to keep the water quality within the parameters most important to the delicate marine life in your aquarium.
Use the new dosing calculator for an easy determination of the required amount of salt for your aquarium.

BIO-ACTIF Meerasalz / Sea Salt
Regular price $89.99Features:
The unique sea salt with bio-active marine agents.
Tropic Marin® BIO-ACTIF Sea Salt contains naturally occurring marine biopolymers, which support the microbiological conditions in an aquarium and thus protect and enhance the growth of aquarium fauna.
To this end, corals will exhibit their bright and vibrant colors in a natural way, while skeletal growth and/or the growth of stronger tissues are promoted. The reserves built up in this manner ensure that corals are more robust and less sensitive than otherwise. Fish also benefit from the bio-active substances by the formation of effective protection against damage to mucous membranes. Fish will exhibit their heightened sense of well-being by increased mating and reproduction activity.
Tropic Marin® BIO-ACTIF Sea Salt can be used by first-time and seasoned aquarium owners alike and ensures stable conditions for aquarium life.
Benefits:
Contains natural bio-active marine substances with a protective and growth-promoting effect.
Develops a sound microbiological balance which stabilizes the water quality and supports the nutrient intake of invertebrates.
For reef tanks with carbon dosing and to create an ultra-low nutrient system.
To maintain the alkalinity in a 8-9 °dH range.
Made with pharmaceutically pure salts, which has the most stringent quality control measures for the production of pharmaceuticals.
All main and trace elements as well as bio-active substances native to tropical sea-water contained in a natural formula.
High solubility in water.
Free of nitrates, phosphates and other unnatural enrichment additives.
The ideal foundation for the care of even the most delicate fish and corals.
Highly compatible with all components of the Tropic Marin® BIO-ACTIF SYSTEM / BIO-ACTIF PROFESSIONAL Line.
How to use:
To achieve a salinity level of 32-35 ‰ (psu), dissolve 35 ml of Tropic Marin® BIO-ACTIF per liter or approximately ½ cup of Tropic Marin® BIO-ACTIF per US gallon water. Dissolve almost all of the salt in a clean container already filled with the full volume of RO/DI water at a temperature of 73-77 °F / 23-25 °C while circulating/stirring the water. Do not concentrate the mixture by adding the full amount of salt to a smaller amount of water.
Note: Always add the salt to the water, never the water to the salt. Making a concentrated mixture will cause a calcium carbonate precipitate to form.
When you have added ALMOST all of the salt and the mixture is fully dissolved, start measuring the specific gravity with a hydrometer or similar instrument.
Note: Slight cloudiness is normal at this stage and indicates that the bio-active substances are taking effect.
Keep adding small amounts of salt until the specific gravity is the value you desire. The specific gravity of the sea salt solution should range from 1.025 to 1.027 (at 73-77 °F / 23-25 °C) and the pH -value should be in the range of 8.0 – 8.4. If all parameters are correct, the salt water is ready to use.
