Re: [APD] Water Hardness and PH
No, CaCl2 and MgSO4 should not affect pH. Just curious, your GH is low but your KH is around 7?
I add the CaCO3/MGSO4 after water changes - GH and KH go from around 1-2 to 5-6very quickly. I've never seen a problem.

thanks for your help...
I am very careful about this because I had once given my fish PH shock
therapy so bad that, they all jump out of the tank. A few more
questions...
If I am to use CaCl2 and MgSO4 instead, should it effect PH and KH in anyway?
If I increase GH level to quick, will it harm fish?
thanks again
