Hi Grouper and welcome. By saying you have a coral bed, I am assuming that you mean crushed coral? If so, some say that they are nitrate traps as they trap detritus and propagate nitrates. I have some CC in my tank but the majority is sand. I use the CC as a calcium buffer.

Depending on the corals you are keeping, nitrates might not be an issue. Inverts, on the other hand, don't like high nitrates.

Good luck and keep us posted on the status of your tank.
