![]() I did put a full sheet of egg crate underneet my liverock and it is fine as long as you wish to keep the sand. If you ever want to remove the sand, then you'll have to rove the egg crate and all the liverock to do so...no fun.
In my case it really helped to anchor my liverock and it would not be as stable if I had not put this. It does protect my bottom glass too. |
