So, I’ve been having trouble keeping my pH stable recently, so I was thinking about putting cuttle bone in there. I heard that calcium carbonate stops dissolving at a pH of 7.4 which is a perfect pH. But I couldn’t find what happens after that. What if pH keeps rising? Will it keep pH from rising above 7.4? How does this work? How do I prevent pH spikes that go upward of 7.4?
