Hi,
I seem to be having a hard time to keep the pH down. This is a 140 gal tank and equipped with a sump and a wet/dry filter with Bio Balls. The hardness is very low something like 2 dH for both kH and GH. I think I don't have enough CO2 in the system. I know at 7.2 is not really a problem, but if I use my tap water which is at about 9dH, the pH will raise to about 7.6/7.7...
I used peat in sump tank and it was no help. The only thing seems to lower the pH was by using Discus buffer from SeaChem. Then again, I can't use the buffer forever.
Any suggestion?
Thanks
David
