Outrageous Phosphate Levels
I have a severe phosphate problem. Until recently, this calendar year, I hadnít paid attention to phosphate levels. Since January my phosphate level has been off the chart for any test I used. Iíve measured my tap water several times to verify that the tests werenít defective. My tap water is about 1.00ppm. My other numbers are good (GH 5, KH 7, ammonia 0, nitrite 0, nitrates between 20-40). Iíve done two major (35%) water changes two days in a row; weekly about 20%. When testing on the third day I had to dilute the aquarium water with RO/DI water and use a Hanna phosphate high range colorimeter to calculate an amount of 59.7ppm.
I have a minor amount of algae in my Anubis leaves and some sporadic brown algae. But no algae problem. Nothing on the glass.
Iíve been trying to treat with various phosphate removers. In my FX6 canister filter and a BRS media reactor.
I canít imagine what would be producing so much phosphate.
