I am going to assume that you have a contiuous siphon type overflow. If the problem is that they are jumping into it I have seen a solution that may work. One person I know of with a wet/dry had the same problem and he put pantyhose over and around the siphon box. If they jump onto it they quickly flip their way off. I suppose you could also use a media bag or anything like that. Strange thing was, he wasn't married and didn't have a steady girlfriend......so I was afraid to ask where he came up with the pantyhose at.

Some things I just don't want to know to keep my sanity.......
