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

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

The API® Phosphate Test Kit tests phosphate levels from 0 to 10 parts per million so you can easily monitor the condition of your aquarium water and can be used in both freshwater and saltwater tanks.

Contains 150 tests and includes 2 test solutions, easy-to-read instructions, a glass test tube, and 2 color charts.
