Nitrate Profi TestWhen there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium...

The Salifert Profi Test NO² -Nitrite- is for the exact and determine of the Nitrite content in freshwater, seawater, osmosis water or water from garden pond. Nitrite is a substance that is very toxic to fish and invertebrates. It is a misconception...

is highly essential for all life forms. Especially corals and marine fish require oxygen concentrations at saturation level. This is because of the low solubility of oxygen in saline water which is approx. 5 -...

pH TestThe pH value can have a major impact on the growth of corals and calcareous algae and on many biological processes. The pH should not be allowed to fluctuate more than approx. 0.3 units...

Salifert Phosphate Profi Test If phosphate is present in too high a concentration there may be an increase in growth of undesirable algae and if the phosphate level is higher than 0.04 mg/L the growth...

With the Salifert Profi Test Si you can determine the Silicate content in freshwater oder seawater exactly and easily. Silicate occurs especially in tap water or in purified water when the RO or DI unit is not functioning properly....
