Phosphates are what feeds algae and helps it grow. Test for phosphate once a week as the concentration in the water can develop rapidly due to rain, debris or bather load. 

Packaged in a convenient and sturdy plastic bottle, the AquaChek Phosphate kit includes testing powder pillows, sampling vial, color chart and directions. The test gives accurate results after only 60-seconds, and measures phosphate from 0 to 1000 parts per billion.

20 tests per bottle.
