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.

At the same time it is a valueable plant nutrient!

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 and may be used in both fresh and saltwater aquariums.



Contains 150 tests and includes 2 test solutions, easy-to-ready instructions, test tube and 2 colour charts

Steven W. ★★★★★

I’ve been fighting green water for months, and this test kit finally let me measure the phosphate levels accurately. The clear color chart makes it easy to match results, even under my tank’s blue LED lights.

Lucy D. ★★★★★

Finally I can actually see what's feeding the algae instead of guessing. The test results are super clear when I compare the vial to the color chart, and it takes less than five minutes to get a reading.

Daniel ★★★★★

This test kit gave me clear readings right away, which helped me finally identify why my tank kept getting green water. The instructions were straightforward and the color chart made it easy to tell my phosphate level. So glad I picked this up.
