Makes it easy to monitor the ammonium/ammonia level in fresh and marine water

Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value.
While ammonium is mostly harmless, ammonia is toxic to fish.

The sera NH₄/NH₃-Test allows monitoring the total concentration of both (the actual ammonia level can be calculated according to the pH value the using the included chart).

Ammonia is the natural waste product of fish metabolism and will accumulate in the aquarium to toxic levels, killing the fish. Fortunately, beneficial bacteria in the biofilter will break down the toxic ammonia. However, there are two forms of ammonia that occur in aquariums: un-ionized ammonia (NH₃), which is the toxic form, and ionized ammonium (NH₄⁺), which is essentially non-toxic.

The higher the pH and temperature, the more toxic ammonia becomes which is why it is really important to monitor cichlid and marine tanks closely. 

In case of acute danger, dose your aquarium with sera toxivec (freshwater).

Sufficient for approx. 60 measurements.

The Hanna Marine Low Range Nitrate Checker^® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Marine Nitrate Checker^® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

• Compact, Portable Design
• Built-in Timer
• Saltwater Compatible

The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.

Features at-a-glance:
Easier to use and more accurate than chemical test kits
Dedicated to a single parameter
Small size, big convenience

Makes it easy to monitor the nitrate level in fresh and marine water.

Ammonia is the most significant dissolved waste in an aquarium. It is produced by fish wastes, rotting leftover food, and decomposing plant matter. The bacteria in your biofilter convert ammonia first into nitrite and then into nitrate. While ammonia and nitrite are highly toxic to fish, nitrate is much less so. However, as nitrate accumulates, fish will eventually be affected.

The level of nitrate cannot be detected directly, as it is invisible and odorless. An algae bloom usually indicates high nitrate levels, though algae is able to grow in newly set-up tanks with nitrate levels as low as 10 ppm

Many fish will not show any symptoms of nitrate poisoning until the level reaches 100 ppm or even higher, but studies have shown that long-term exposure to sub-critical concentrations of nitrate stresses fish, making them more susceptible to disease, interfering with the growth of young, and decreasing the likelihood of reproduction.

When nitrate levels rise to completely intolerable levels, fish will become lethargic and may have open sores or red blotches on their skin. It is common for fish kept at high levels to die suddenly, and often when a new fish is added to an aquarium in which the fish have gradually become accustomed to high nitrate concentrations, the new fish quickly dies from the shock.

Hanner - Marine Salinity Tester HI98319

Designed to bring simplicity to salinity testing during the any process, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD.

The HI713 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate. Phosphate is a common food additive that enhances flavor and acts as a buffering agent. Important for growth and development of plant roots, phosphate is also present in fertilizers. However, high concentrations of phosphates are detrimental to the environment; for this reason, it is closely monitored in natural and municipal waters. Designed as a more accurate alternative to chemical test kits, the HI713 provides quick, accurate results in a few easy steps.

Calcium requirements tend to increase in most reef aquariums as they grow and mature. As a result, your old supplementation regimen may no longer be adequate. If regular testing is not performed to monitor calcium levels, it is very easy to allow levels to drop precipitously. In reef aquariums heavily stocked with corals and invertebrates, it is crucial that calcium levels be assessed every two weeks; or even better, once a week. Alkalinity should also be measured and monitored since there is relationship between calcium and alkalinity levels

If calcium levels get too high (over 500), there is a tendency for alkalinity to drop, affecting the buffering capacity of your aquarium water. Without adequate buffering, pH levels become susceptible to fluctuations. Conversely, if alkalinity gets too high, calcium levels will tend to fall as calcium precipitates out of solution in the form of insoluble calcium carbonate, also causing pH fluctuations. Ideally, calcium levels should be between 400 and 450 ppm, while the alkalinity should be between 2.5-3.5 meq/L (7-10 dKH).

It is important to monitor calcium and alkalinity levels weekly and supplement accordingly to keep them at proper levels. Low calcium levels negatively affect the growth, health and coloration of corals and what little growth that may occur result in thin, spindly branches lacking vivid coloration.

For monitoring magnesium levels in marine aquariums easily and safely. 

Marine:

Often overlooked, magnesium plays a critical role in chemical and biological processes in an aquarist's saltwater aquarium. The magnesium content in natural saltwater is only behind that of sodium and chloride, making it a major element as opposed to a trace element. Magnesium is essential to all organisms for biological functions, and is very important to organisms that are skeleton building such as LPS and SPS corals.

Before dosing anything, you need to know where you're starting, so test your aquarium's water. Magnesium levels in a reef aquarium should be between 1250 and 1350 ppm. Since each aquarium is different, it will use magnesium at its own rate.
