I have a 1 year old 58g oceanic tank, set up with live rock, fish, and some softies. I want to add a sump under the stand but didn't realize how little room I have. Any one have a similar setup with sump and skimmer. Clearance on front door is 10" wide and two openings in back of approximately 11 1/2" each. The inside room for sump and skimmer is 32" L x 14" d x 23" h. I need suggestions for sump size and skimmer. It became obvious my Aqua C Remora Pro won't fit.
