We setup a new 32G tank with gravel. Water pH was 7.2. When we added rocks (sold as "lace rock" from LFS), the pH shot up to 8.4. To verify the rock as the cause, I put a fresh cup of RO water and tested the water before and after adding a small piece of rock and confirmed the pH went up by exactly 1.2.
Thinking that perhaps soaking the rocks would clear it up, and rather than waste the water, we just left it in the tank for a week, and then did a 100% water change.
LFS said to get BB cycle going and to focus on pH later. So we did. Just completed the cycle and pH is at 8.0. We have also added live plants since the initial setup (moneywort, Java moss and anubias nana).
Of course, the fish we are looking to add, all want more acidic water. I also know altering pH by other means is not consistent nor easy to maintain. I also know fluctuating pH kills the fish.
So.... What can I do? Can I do a large water change now that my cycle is done? Should I remove the rocks and get something else? If so what?
