I have aprox 50 gallon water in my system. I had done a 2 1/2 gallon wc and changed my carbon (BRS rox .08) and gfo (Rowa) . My parameters did not swing but my phos went from 0.07 to .0.00 in 2 days and 1 of my sps bleached (Purple effo). How do I avoid the rowa gfo pulling the phos out to fast . I have a dual brs reactor and I do not have it on hi flow. should I use less gfo , I used 4 tbs?
