eggcrate

After having a heavy metal poisoning with another diy project I just wanted to make sure that egg crate is reef safe. I'm almost 99% sure it is but just wanted to Verif. Reason I ask is I made a very crude but effective cover for my powrrhead to keep my anemone out lol.

I purchased a panel of eggcrate for the bottom of my tank, hoping that this will help keep my sand in place a bit better. I am having some trouble trimming the plastic to form, since it is so brittle. I used a scissors to cut across, but still have some small pieces which are fairly sharp...

Where in the world can I get egg crate for my frag rack!? Lowes doesnt know if they have it and neither does home depot. A little help please.

1) where do you find the eggcrates that hold your standard frag plug? 2) anyone have specific instructions on constructing a small eggcrate (the size of a small shelf like 3" by 6") to suction-cup to the glass wall? ...meaning how do you mount suction-cups to the eggcrate? ...heres the deal...
