Will the reduction of PO4
cause a shift downward in PH
? I have been on a sucessful cyno battle and have basically eliminated PO4
from my system and my source water. The cyno and hair algae is all but gone now but I have noticed that my PH
has dropped from the usual 8.2-8.3 down to 7.9-8.0. My alk
is a steady 3.5+.
I have added another #40 of LR
recently and doubled my sand bed to a depth of 4-4.5". One would think this should help.
All these changes have been recent, should I just give it a little time or start buffering?
Also my fresh salt mix measured at 8.25.
