I setup my 55 gallon with pool filter sand, some silk plants, and boiled rocks from my yard. I thought all the rocks were granite but apparently one of them wasn't.
My water comes out of the tap at
pH 7.5 and my pH in the tank is 8.0. I'm guessing this was the rocks so I removed them. I now have 6 cherry barbs in the tank that seem to be fine(currently cycling with safesmart) The issue is that when I do a
water change the pH of the water I'll be putting in will be different than whats in the tank.
Any suggestions on how I can get my tank water back to 7.5,which is the tap pH, without stressing my cherry barbs.
thanks
