Bio media for Mbuna's

Hi all,
I have some dry skeleton coral rocks and I was wondering, could I break them up into smaller pieces for use as bio media in a canister filter to help maintain my ph for Mbuna's? Also will bacteria grow on them?

I know dried coral can help with raising ph but I've heard beneficial bacteria doesn't do well with it, although I really don't see why it wouldn't. I know people put dead coral right in the aquarium for raising ph but I don't know about putting pieces in your canister filter. Dried coral has a tendency to shed small pieces especially if you break it into pieces to fit in your filter. I would be worried about tiny fragments getting to the impeller. If you did try it in your filter I would use a fine mesh media bag to put in it just to be safe.

What kind of filter are you using? What is the ph level in your tap water?

I've used seashells to help raise ph in my aquarium water. You can use whole shells or broken pieces.
