Wow. That sounds like it would keep out a lot of stuff. I am too scared a algae floatie would clog that up and nothing drains!
I might try it with my leftover 1/4" clear screen though
The only sump jumpers I had were the clowns when Moby was here.
Sadly I don't have a screen on the little tank and I lost an anthias last night because it just jumped out of the tank :(
I'd much rather would have found it in the sump.
