I have four res's all four go from 5.5ph to 4.0ph overnight. This just started yesterday. I freaked out this morning and changed the res's, and left them untreated (no ph down) at 6.3 ph. I added 4 TSP of H202 in each the 10 gallon res's for I'm suspicious of possible bacteria, the roots look great though...? I'll be going to the hydro store for some ph up, never in my right mind thought I'd ever need it for my water I use is so high in ph. Anyone have any thoughts? Thanks
