I am going to have to try and figure out what skimmer this is. Looks older, not transparent (kinda white), probably 2' tall...it had the Rio on it and he said it skimmed great, I've just never been a Rio fan. I will look into Quiet Ones too.
I'm still trying to figure out how to set up the sump and refugium...I've got a 35g acrylic tank, a 45g acrylic tank and this 240g came with two CPR Aquatics two chamber wet/dry filters (1000). He had one running as it should and then he had that connected to the other, which just held the skimmer and then the return back to the tank. I've got four "containers" and an 8'x2'x2' tank.
I'm thinking about having one of the CPR's as the mechanical filter (thinking of converting to a sock instead of how it is now) maybe add some live rock...then connect that to the second CPR and use that just for the skimmer...then add either the 35 or 45g (with some customization to add chambers) as a refugium...then return pump back out to the tank. That gives me 30g + 35-45g under the tank. Would that work okay???
