I have 2 Remora Pros...one on my 65g reef and one on my 50g FOWLR...the one on the reef has never ever had an overflow oops....the one on the FOWLR...my fault totally but it did overflow...I used to use a chlorine remover with slime coat protector...WRONG idea...skimmers go nuts with this...so walked away from tank, had collection cup really really low, and OOPS it got so filled that it was coming out the cup...and yes I did end up with water on our newish laminant floor. But they are fantastic skimmers, my fault with the overflow issue. I would recommend them any day, and I have had the one on the reef for over a year! Hope that helps...if not well at least someone may be able to laugh a bit at my oops!
