I know MR hosts a bunch of creative minds and was wondering other than for frag racks, filter sock holders and flying fish prevention, what other uses have you found with egg crates?
I have some left over egg crate and want to utilize it for something in the hobby.
I put pickling lime in my top-off container so I put the pump on a piece of eggcrate to keep it from sucking up any of the gunk that builds up on the bottom.
