API Phosphate PO4 Freshwater & Saltwater Aquarium Test Kit, 150 count

Phosphates can enter your aquarium through tap water, fish waste, and decaying organic matter such as uneaten Food and dead algae. Excess phosphate contributes to unsightly algae blooms and green water, and in saltwater, excess phosphate can inhibit the growth of hard corals.

The API® PHOSPHATE Test Kit tests phosphate levels from 0 to 10 ppm so you can easily monitor the condition of your aquarium water and can be used in both freshwater and saltwater aquariums.

It contains 150 tests and includes two test solutions, easy-to-prepare instructions, a glass test tube, and two color charts.
