The pH in my cichlid tank is lower than I'd like, and I was thinking about swapping out the gravel for crushed coral or shells. I have two questions.
First, my cichlid likes to move around the substrate in the tank to his liking. He shifted ALL the gravel out from under his caves and put it in the front of the tank (you can see the glass under the rocks). Is crushed coral or shells dangerous to him if it has jagged edges?
Second, how do I properly introduce new substrate to the tank? Will it disrupt the cycle or shock the fish if I put it in right away?
