So, I hope this thread goes here… If it doesn’t I apologize. I know there are many ways to change the PH of an aquarium. In my main tank I have a pair of rams. They are breeding but enjoy the eggs as snacks and such. I’m not sure if PH is the cause (the PH is 7.5 but rams enjoy 6.5ish) and I would like to know what kind of rocks I can place in the tank. (or any other object) I have 2 drift wood pieces witch helps. I prefer to avoid chemicals because nature does not use tetrafin . I have tried to find ways... but alot are chemicals and I havent had much luck.. ill keep looking.
