i purchased some bulkheads and a pair of 27gal sturdy storage bins at Home Depot this past weekend. I also purchased some pvc with which i fashioned a pair of air-driven skimmers to put in them, or one of them. I am thinking deep sand bed, macro-alge w/24hr lights, and open space for settling. without getting too intricate, does anyone have any suggestions for how i should arrange this? im planning to set it up above my sump, which will contain a return pump dedicated to the fuge, allowing the fuge to just overflow back into the sump. thats the extent of my decisions thus far. i dont know if sand, skimmer or algae should come first, or what order they should be arranged, or if it even matters. thoughts?
