hi folks
i tested by PH today using PH paper brought from aquastar.
it was roughly about 7.5 to 7.6
i am using coral sand and coral chips to make my PH higher and stable.
but this does not seems too effective.
how do you make it go to PH 8?
i saw some bags of oyster shells from clementi C328
can oyster shells raise PH to 8?
what other natural substance and raise the PH to 8?
i have some reservations about PH buffer and chemicals...
and what about the african cichlids salts?
what do these salts do?
thanks
