Keep your fish healthy and thriving by testing your aquarium water's PO4 3- levels regularly with this easy-to-use API PHOSPHATE TEST KIT for freshwater and saltwater aquariums. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. Phosphate enters the aquarium from fish and invertebrate waste and decaying organic matter, such as dead algae and uneaten fish food. Excess phosphate contributes to unsightly algae and green water blooms. In saltwater, excess phosphate can inhibit the growth of hard corals. API PHOSPHATE TEST KIT for freshwater and saltwater aquariums contains two phosphate test bottles, test kit instructions, one capped test tube, and two color cards to accurately measure phosphate levels in fresh and saltwater aquariums.

Phosphate enters your 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. Some salt mixes also contain phosphates. Excess phosphate may lead to algae blooms. In saltwater aquariums, phosphate precipitates dissolved calcium and magnesium, inhibiting the growth of hard corals and other reef-building organisms. This test kit reads the total phosphate level in parts per million (ppm), which are equivalent to milligrams per liter from 0 – 10.0 ppm.
