Hey guys I need some help. When shopping for a skimmer what does the foot print represent? I'm trying to.figure out if the skimmer I chose will fit in my sump. I have a 30 gallon oceanic sump 36x13x16 and I want to purchase an Aquamaxx Cone 2 which has a foot print of 13x8. Will the skimmer fit? Any help is greatly appreciated.
