PRODUCT SUMMARY
Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneaten food and dead algae. Excess phosphate contributes to unsightly algae and green water blooms, 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 that you can easily monitor the condition of your aquarium water. May be used in both fresh and saltwater aquariums.
We recommend that you take a few minutes each week to monitor your aquarium conditions and create a better underwater world for your fish. Testing your aquarium water has never been so easy or accurate!

I’ve used this kit for three months now and it’s very reliable. The instructions are clear and the results are consistent. It helps me keep my freshwater tank balanced and algae growth under control.

The test is easy to perform and gives accurate readings. I noticed less green water after starting weekly tests. It’s a small investment that pays off in tank health.
