Says who. !" can be too much in some conditions. Unless yu have a
need for a deep sand bed its best to keep it at or under 1" and not
worry about it causing problems later on. However if there is a real
need for a deeper bed then 2" is really too shallow, but its deep
enough to cause problems.

How can you tell if there's a need for a deeper bed? I have an 8- or 10-gal.
hex tank set up with about a 3" bed.
