Hey Aq-Co!
I'm hoping someone there may have some input/perspective for me.
What I am trying to do is use rubber lawn edging as a substrate stabilizer to build up a deeper tier in the back of my fresh water tank. I have plants I want to put in the back with out all the sand being as deep as I want to them.
I found this really cool, very thick, self standing lawn edging at Wal-Mart. It says it's "100% made from recycled tires". Do you think its aquarium safe? I thought about just covering it with silicon completely, basically sealing it. Its a tougher more porous than slippery rubber.

I am in mid project with 5 tanks and now I am second guessing this product.
Any thoughts?
