This liquid kit is used to test for phosphate in the water. Often used to see if your source of water has phosphates in it. Used a lot in freshwater planted aquariums and saltwater aquariums. Too many phosphates is one of the leading causes of algae in an aquarium, however it is also a building block of plants.  Kit provides 150 tests.

Honestly I have had fish for a many years and until recently never knew you should test for phosphates. I've been having an algae issue and after watching one of Corey's videos he talked about phosphates... guess what I have a lot of phosphate right from the tap water. So I also purchased the phosphate media in hopes it will help my slight algea issue.

It tested my phosphates

API's liquid test kits are always good. Price here was better than my local fish store. Yay.
