SeaTest densimeter SeaTest densitometer, description and features: Densitometer The SeaTest densitometer is an easy-to-use scientific instrument for measuring both the specific weight and density of tropical marine aquarium water. It is specially designed to accurately measure specific gravity from 1,000 to 1,030...

Testeur d'eau SeaTest MG SeaTest MG water tester, description and features: Magnesium Mg represents the 3rd most important element in the composition of seawater. It is essential to many biological processes, including photosynthesis and cell division. It is also involved in the formation of the skeleton of reef organisms. Keep out...

Testeur d'eau SeaTest CA SeaTest Ca water tester, description and features: Calcium Ca is one of the essential components of seawater. Corals, invertebrates and useful red calcareous algae consume the calcium present to build their skeletons. Ideal concentration: approx. 400 - 450 mg/l. Check calcium levels...

Testeur d'eau SeaTest PO4 SeaTest PO4 water tester, description and features: Phosphate PO4 is a residue from the breakdown of organic matter such as food scraps, fish droppings, etc.... It can cause algae proliferation. Although it is preferable to keep PO43- values as low as possible, values of up to 0.5 mg/l are tolerable....

Testeur d'eau SeaTest NO3 SeaTest NO3 water tester, description and features: Food waste, fish droppings and other organic matter containing nitrogen are broken down by bacteria during the nitrogen cycle into ammonium, and then into toxic nitrites. These are then transformed by other beneficial bacteria into harmless nitrates in low concentrations. In a...

Testeur d'eau SeaTest NO2 SeaTest NO2 water tester, description and features: Food waste, fish droppings and other organic matter containing nitrogen are broken down by bacteria in the nitrogen cycle into ammonium, and then into toxic nitrites. These are then transformed by other beneficial bacteria into harmless nitrates in low...

Testeur d'eau SeaTest NH4 SeaTest NH4 water tester, description and features: Ammonia NH4 is a chemical compound that is normally transformed into nitrite and then nitrate in the nitrogen cycle. If this is not the case, then the nitrification process is not complete and biological processes are not taking place as they should....

Testeur d'eau SeaTest pH SeaTest pH water tester, description and features: The pH is one of the essential values for a healthy aquarium or pond. The pH value reflects the ratio of bases to acids present in the water. As a result of biological processes, the pH value of water can change over time. As the inhabitants of aquariums...

Testeur d'eau SeaTest KH SeaTest KH water tester, description and features: Bicarbonates (KH) have a stabilizing effect against variations in water pH. As a result of biological processes, water KH and pH values can change over time. As the inhabitants of aquariums and ponds are extremely sensitive to any change in pH, regular checks of the...
