Rock

[CurtisL]

can you have too much rock in your reef? is it bad at all, or the more the merrier?

Usually, rule of thumb is 1-2 lbs per gallon....I think there IS such a thing as too much if your fish have no room to swim LOL Unless you want a rock tank?

The more rock you have, the more bacteria your tank can process. There is a balance though, eventually there can be too much for some fish to swim comfortably.

too much rock is a detritus trap, where it sits on the sand anoxia can produce sulfides, the main issue is how to develop flow for the corals

so say 2lbs per gallon max is safe?

Yep that's the general rule. When I started my biocube I had 58 lbs. In a 22 gallon area and to me it was way too much rock I took out several pieces to make more room and a few months ago I took out even more for more open space swimming.

rock is very variable for porosity, some is almost dead weight some is feather lite so the lbs per gallon is a little open to interpretation
