having problems deciding which skimmer I should get. build will be a 90 g marineland reef ready with sump. I already have the lights and the pumps. not going to use my HOB eshopps psk-100H. going with a different protein skimmer. my first question is difference between AC pumps and DCV pumps. I will either be hooking up a co2 scrubber to it or running an airline to the outside 25 feet with a half inch diameter pvc pipes. cheaper than using hoses. then I am looking at the red sea 600 skimmer, skimz sv227 Oval DC nternal protein skimmer, or reefoctopus Super Reef Octopus SRO-3000INT 8” In Sump Protein Skimmer. Just can't decide. educate me please.
