AquaChek One Minute Phosphate Test Kit

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. For use with phosphate removing products such as ZeroPhos, PHOSfree, or Lo-Chlor Starver.

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.

Only available in US.

20 tests per bottle.
