Clips for Eggcrate on a Rimless Tank

[Reef Pilot]

Actually, if it is just the egg crate that you want to seat in place on your rimless tank, you could do it without any clips at all. Just cut it so that it is overhanging the tank by one hole, and then clip out the bottoms all around so the top of the egg crate is near flush with the top of the tank. Then it will be seated in place and can't slip off.
