Egg crate below sand?

IMO if you were doing BB then it would be nice to support the rock off the bottom to allow more circulation. Being your using sand I'd think with all the weight of water, sand and rock is normal and should be an issue. Now if your thinking a plenum, that would be another case of study! :nerd:

Merry Christmas!

Thank you for the reassurances And Merry Christmas to you as well

You could cut a piece of plywood for that couldn't you?

I did conceder this but any alterations void my warranty. Plus you would be able to see it with the rimless tank
