Thanks for the info Jesse. It would be for a 65G with TBD stocking level, and a basement sump, so noise level is not a concern. The BB pumps are pretty good pumps. I dont like the XP1000 SSS with the pump underneath and a very small looking body above it. The SRO looks like a better design. The In100 with a better pump is a nice skimmer. I wish Vertex and ER would ditch the Resuns and use better pumps.
