Phosphates are a food source for algae; the more phosphates in your water, the more algae comes to feed on them, which leads to green-tinted water. Using our test strips to check your water, helps you to prevent green water and added chemical costs—avoid having to add even more harsh chemicals into your water! By investing in phosphate test strips and a good phosphate remover, you will save time, money, and frustration.
