Hello, I just received my new Hanna Phosphate checker tonight. I did two tests of my water and got 0.00 both times. I don't have an algae problem, but I definitely have a small amount of algae in the tank, meaning there has to be some phosphate. I know that you can have low readings when the algae is using the nutrients, but 0.00 in the water column?
Has anyone else had this issue? Am I doing something incorrectly?
