So I've been 'stalking' this fourm for a little over a week now, and I would first like to say that this place is amazing -- there is so much information, and its a great help being that I'm a beginnger to the hobby...anyways...

I have 72g tank with wet/dry filter, and almost more live rock than my tank can handle. I'm wondering if it would be a good idea to take out the bioballs and replace it with some of my live rock. Does this sound like a good idea or any suggestions on how to modify my sump? (Here's a pic of what it looks like)

From what I've read I'm assuming that most people don't like bioballs...why is this?

Thanks.[/url]
