top drip system 20 g reservoir and i can't keep my ph stable. every time i check its back up to around 7.5-8. have some sodium biphosphate that brings down the ph in aquariums...ok to use in my system ???? using rockwool blocks and slabs. can't figure out why the ph is constantly on the rise. normal ??? 1st time hydro grow.using advanced nutes and let my h2o sit for 24 with airstones prior to using.
