I'm designing the sump for my 180.
I was originally going to go with a single 48" acrylic tank from glasscages.com, with a skimmer area, a return area, then a fuge area, which would get water from a small pump in the return area, and overflow back to the return area with a bulkhead at the top of the baffle.
But, now I'm thinking about a separate tank for the fuge and sump. Same setup, a small pump in the return area would send water to the fuge, which would be raised over the sump a foot or so, and drain via a 1" bulkhead back into the return area.
This would give me the flexibility to adjust fuge size down the road, and have a larger return resevoir, and more room for heaters, UV
, sump socks, etc in the sump.
Also - how hard is it to drill a bulkhead hole in acrylic? I might just buy a standard acrylic aquarium, and glue the baffles, and add the 2 bulkheads for return pumps myself. I know glass takes special considerations, but what about acrylic? I've never done anything with it except cut small pieces with a hack saw...
