Reef safe screen???

[BrianG]

I have frags and loose polyps that will fall clear through egg crate. I always see some sort of screen material used to prevent such an ocurrence, is this the same stuff you get at Home Depot for windows? Thanks!

Maybe some of the plastic canvas you can gt at Walmart or a hobby store for crafts?

If you go for a mesh to cover the egg crate, make sure it's a polyester mesh and not nylon. I'm looking for the reference links, but there's been some studies that show polyesther is better than nylon. Inert plastic is probably the best if you can get a hold of it.
