Skimmers & other filtration
I have a 70 gallon tank with a 15 gallon sump that I will be setting up soon. The sump has 3 chambers and I want to put a protein skimmer in the first, and a refugium in the second. The 3rd feeds the return pump.
The problem is that the first chamber of the sump has a 10.5 x 6 inch footprint...
