I hope this isn't hi-jacking this thread, but I'm a bit confused with some comments made about moving rocks to the sump. Coral girl said in post #9 that's she's only got 150 lbs of rock for her 180 gallon. Given that the go to answer for "how much rock do I need?" is roughly 1-2 lbs per gallon I'd hardly call that over kill.
I would agree with Albert that there is a point that more doesn't do any good, but in my limited experience, I wouldn't have thought this tank was really there yet. The original question was about moving some of that 150 lbs of rock to the sump so there was more room in the display tank, not adding more rock to the display to get more filtering capabilities.
If the bacteria on 150 lbs of rock is processing all the tanks parameters well, I do not understand why it would matter where the rock is. If someone really likes the look of sand flats and the creatures that lived there, what would stop them from having no rock in the DT and 150 lbs of it in the sump? As long as there is proper water flow and maintenance in both tanks, there's no reason why it wouldn't keep water parameters in proper alignment, no?
I'm not trying to be argumentative either, just curious for my own benefit and others following along. Help me understand
