I did put 6oz of algimycin 600(poly ethylene dichloride) and one box of borax .The filter pressure is 20psi as it was at last backwash and new DE.I ran out of DPD powderdoing this last test. I have some ordered expect it in a day or two. The only other test I have is an OTO kit that only goes to 5-10.
