So finally, just starting to get my pre-cooked live rock in the tank and starting to fill it. Question is about my sump. Going to have the filter socks on the left with the protein skimmer, fudge in the center and I’m wondering if I should put sand in the center or I have those pieces of Marco rock also. Or both? I’m thinking about having a cleanup crew in there also as well as some macroalgae. If that sounds right.
