I was curious , should my skimmer run 24/7 or just so many hours a day ? I have RedSea Prizm HOB skimmer rated for 100 gallon tank on a 60 gallon acrylic with built in sump. I have 1 Diamond Goby , 1 Perc , 1 Sailfin Tang , Blue Tang a few peppermint shrimp ...emerald crabs and various snails and a bunch of easy to keep coral . I have been getting conflicting advice from different friends .
