Just bought a 180 gallon complete system. Changed the skimmer out for ASM g3. My problem now is dunno how I wanna do the sump. Currently it's run by a small 25 gallon wet dry with balls removed an skimmer in its place. No room for anything. I want to use a 100 gallon stock tank and 45 long for green refugium and possibly mangrove tank. Any suggestions on doing such? Here's few pics for the sharing of what I have going at this time 1week after the 70 mile move.
