i'm been using hygrozyme and greatwhite so don't bother telling me about them. I got the roots to warm after a nuet change now i've got rot. I took the advice of ob-1 to use h202 according to manufacturers spec and it seems to have helped a good bit but bulk of it still remains and am considering using a higher concentration. the rot is causing my ph to run high in only a few hours (5.5-7.2) .Any EXPERIENCED ADVICE would be appreciated.
