I have a Classic 150INT 6” reef octopus skimmer lying around for when I had enough money to properly set up my 120gal nicely. I have a 40 breeder lying around which I was thinking about setting up. I was gonna have a 29gal that I would set up as a sump. I was wondering if this skimmer would be too large and not work right for this system. I've read that having too big of a skimmer can lead to it not working correctly.
