I have a new-style BioCube and have heard the bio-balls are about useless(and I agree they didnt seem to be doing anything) So I have removed them, put about 1/4" crushed coral over the screen, put a decent size chunk of live rock and Chaeto in the sump. Im curious what temp lighting I should be using for the chaeto. I plan on just using a clamp-on lamp with a CFL bulb. Thanks!
