I know there is like this AA rule about trying to change ph. My ph is 8/8.2 and I have African cichlids... Gold fish in another tank... Betta In ten gallon. I don't worry about these so much with the ph but I'm thinking of starting a community tank and I'm wondering if I should use some API buffering powder to make it more neutral. I'm wondering if rummynose and other tetras would do bettter? I'm not sure. There are currently no fish in the tank that's the only reason I'm considering this. Any tips? I heard that its pretty stable If u add it with each pwc. Anyone have any experience or advice with this?
