Awesome Cheech...Thanks. The scale really helps. I should be OK with the skimmer, the footprint is 8 1/2 long x 4 3/4 wide, and I will have it elevated off the bottom, so the pump will fit also. I presume the eggcrate is to keep critters from going over into the return pump chamber? Will the egg crate create bubbles into the return? Based on the scale, am I better off using a shallower sand bed with live rock? Thanks for your help everyone!
