So I checked my Ph today for the first time since I put my ADA aquasoil in and it came out to be around 7.8. This is crazy. I have CO2 and I was told that CO2 drops your Ph. Doesn't seem to be happening. My tap water is about 7.8 so i was thinking this is my problem. Should I just use DI water from now on? Whats the Ph of DI water? No wonder my HC hasn't been growing well???
