I just bought a turboflotor hang on skimmer yesterday...225 bucks...kind of insane. But n e ways i have a question about it. The bubbles that come up? Should i set it so they're always coming to the top or half way up or what? Also...my lid to my tank totally doesn't fit over it. How do you guys deal with that and what do u put over ur tank? I'm thinking about just building a sump but i'm freaking out like a champion thinking its gonna overflow onto my expensive wood flooring. Any suggestions?
