Hi I'm new to salt water tanks and reefing. I'm going to be setting up a 150 gallon tank with center overflow and sump refugium but I'm not quite sure what the best way to go about it is or what pumps skimmers and substrate would be the best and weather to keep my old 55 long for a frag tank or hospital tank. And what LEDs are worth the investment. I would rather have an empty unassembled tank than start up the wrong way and harm fish and corals.. All tips and advice are greatly appreciated. Thanks
