Hey guys, I'm looking for a recommendation for a skimmer upgrade. I'm currently running a Reef Octopus 110SSS on a 45 "cube". When I add my sump and subtract for live rock I estimate I have 55 gallons of water. I'll be running the Fauna Marin Ultralith system which relies heavily on skimming so I'd like to get a good, high quality skimmer that isn't too oversized. I'd prefer in-sump but can manage with an out-of-sump if it's worth it. Thanks to anyone who helps.
