Ok so I have 29 gallon tank. 3 Corys 2 longfin serpe tetra 3 neon tetra and 4 mollies. So I made a Co2 system and was told to turn of my air pump so the Co2 would desolve better. After a day with the pump off the PH rose from 7.2 to 8.4 in a day. I turned the pump back on and added another one to get the PH down and its at 7.2 again. Does anyone know how I can keep my PH down without having the pump on. The Co2 by itself isn't enough to keep it down.
