I am looking to get the Super Reef Octopus 2000 but I am not sure it will fit in my sump. I have a 30L for a sump. The dimensions of the sump are: 36L x 16T x 12W. I see the dimensions on the SRO 2000 are 12.5 x 8. Is the 12.5 including the pump or that the size of the body of the skimmer? If it wont fit what skimmer should I look at for a 90 display with 30 sump, heavily stocked?
