Rocking this weekend...

[hunggi74]

Hi everyone. I'm thinking of rearranging the rockscape in the DT this weekend. 57gallon tank with half Marco 1/4 Fiji 1/4 Bali rock. Over 60lbs. in the DT and I was wondering if I could put 1/3 of the rock in the sump as long as I have the room? Filtration is filtration and it shouldn't matter whether the rock is in the DT or sump, correct? Also, most of the Marco pieces are big chunks 10-15lbs. Can I take a hammer to these to break them up? Would the smaller pieces mean more surface area for filtration? Do I place the rock in a heated tub of saltwater with a powerhead going while I rework the scape? I'm not going to be killing anything, starting another cycle am I? Thanks all!
