I think I want an SWC 200 Xtreme. I have a 120g with 40g sump with an estimated 110-120g circulating volume. I want a well built skimmer that can handle a heavy bioload. My current sump's skimmer section has a minimum dimension of 8.5", but I am considering removing a bubble trap wall to make it 10.5" x 17". I have 2 sections after the bubble rock that has chaeto in one and LR in the other before the return. Any input on the skimmer would be good. I would definitely do the mesh mod.
