API Nitrite Test Kit,

Test reads 0 to 10 mg/ or parts per million (ppm) of phosphate. Helps to decrease the likelyhood og having unsightly algae and green water blooms.Test kit of 150 tests.Why test for Phosphate?Phosphate enters the aquarium from fish and invertebrate waste and decaying organic matter, such as dead algae and uneaten fish food. Water treatment facilities may add phosphate to tap water to prevent pipe corrosion and reduce concentrations of heavy metals in drinking water.Unnecessary phosphate may cause an undesirable cloud or tint in aquarium water. In saltwater aquariums, phosphate precipitates dissolved calcium (Ca2+) and magnesium (Mg2+) ions, inhibiting the growth of hard corals and other reef-building organisms.Testing Tips:The Phosphate Test Kit reads the total phosphate level in parts per million (ppm), which are equivalent to milligrams per liter (mg/L) from 0 ppm (mg/L) to 10.0 ppm (mg/L), in either freshwater or saltwater aquariums. There are two Phosphate Test Color Charts ��� one
