Paraphrase: They only recommend 1" of a sand bed "on small tanks" due
lack of real-estate. He didn't say anything about borrowing animal
releasing the bubbles he said the borrowing animals "rasps" could expose
the anaerobic bacteria and cause the ammonia to spike in a dsb. He did
say something about nitrogen bubbles but i don't remember the context.

I'm learning. Sorry for the confusion

I'm considering a dsb in my 45 gal tall tank as it has room. How many
inches do you suggest?

Can I make one suggestion, having read a lot of your recent posts, and
that is maybe go and invest in a book - a really good one is "Natural Reef
Aquariums" by John H. Tullock - others might suggest other reads but I
have used this as a basis for my reef tank research and then supplemented
any questions I have with newsgroups such as this or dedicated reef
forums.

oh i already have books. i like to be social and learn this way. you should
probably just killfile me if i'm annoying you. seems most folks don't mind.
