PH balance for AK-47 and a dwc

Hello friends I am going to some AK-47 I have a dwc I try to keep the pH balance at 5/8 but I am it keeps going up and down up and down up and down is there something on the market that will neutralize it and keep it in 5/8

Nope. This is a natural part of DWC and will always happen. You’ll lol get used to it though, I’m a fellow hydropnics grower (DWC).
