Does anyone use CO2 just to lower the PH on your tank?... Not for Live plants. Just to control the PH.

I have used diy co2 to lower the PH from time to time when I get new fish that have been kept in substantially lower ph water than my tap water. This is only for acclimating them to my water though as I just run the co2 bottle until it stops producing & the PH has climbed to it's usual level.

GH/hardness won't effect co2's ability to lower the PH. It is KH that effects the PH. The higher the KH reading of the water the more capacity it has to buffer against PH swings.

Thanks, I just got my Co2/PH controller with the electronic valve (Tunze) and i will buy the co2 cylinder + the regulator by the weekend. the store didn't have the tunze diffuser so i have to order it from Germany takes time, Instead I'm going to use my power head with a bottle to diffuse the Co2.

Yours,
