To Egg Crate or not?

[Twinn]

+1 on the put the rock down first and then the sand.

As far as egg crate goes I looked over the information before starting my tank build and decided to do no egg crate. I did this because I want all the good little critters in the sand that stir the sand and eat algae, debries to be able to move through the sand. If your sand has egg crate in it parts of your sand will just become traps for all the bad stuff that builds up in sand.

On a side note everyone has heard of rock cracking the bottom panel of glass hence the reason to use egg crate but, I dont know anyone that has ever had this happen to them.
