I have city water. It's 7.8 from the tap I slowly was using the maliwi buffer to bring my ph up to 8.2/8.4 like peruses pets said and lost a few of my peacocks to an ich invasion. I wish I never used it. Should I now contine to hold that ph and continue using the buffer? Can i stop using the buffer and be okay? Peruses said keeping the ph higher (8.4)will help the fish color more, any truth in that? All my fish are doing well now adjusted.
