I have the 65 gallon model on my 30G cube and it works fine. I don't run it 24/7 because it's in my front room next to the TV and it can be kinda noisy. If I run it during the day while I'm at work i can shut it off at night since it's already stopped skimming after just the day. That's just for me. No mods. Never felt it was necessary. Yeah if I turn that level adjuster all the way up it overflows. But I have it set right and hardly ever need to adjust it. Since it's hanging off the back of my tank I've never accidentally turned that knob. HTH
