I have a bunch of egg crate sheets (2' x 4') to trade for frags. I posted a while ago, but not much response. I have 5 left. I'm in Glendale, up Myrtle ave. Not far from you.
I got one off of ebay, cost me about $20 with the shipping included. It's 12"x4"x4", and has an adjustable hook so you can raise or lower it in your tank, comes with a lid also.
Because of how my canop is I've never used it yet, can't hook it to the side of the tank.
It's just sitting with all the other equipment I have that I never use
