Basic PH So for weeks I've been able to maintain my ph between 5 and 6 I change my res weekly today I checked my ph and it was a little in the acidic side so I added "ph up" a ph kit the organix store gave me I added a few drops and now my res is aroun 7.5 maybe even 8 how will this affect my ladies if at all??
