I agree with both of you. I think that live rock and having alot of it is great, buttttttttttttttt if you have food that is not being suspended long enough to be picked up by janitors or by filtration, then you have a seperate issue. I think you have to make sure your aquascaping is shaped in a way that less excess can get caught up. I also take my seio off the glass and "shower" my tank with flow to suspend the areas that contain decaying fish matter to help with the filtration of it. I have my wet/dry which has an HOB overflow. The overflow doesn't filter NEAR as much as decaying matter as my filstar, which reaches about 20 inches down into my tank. Maybe some supplemental filtration is in order?
