dsb clarification

Keep in mind that the frame of the aquarium will
cover up a portion of that depth, so it won't look
as deep as it is.

That's stupid.

Yes a 45 is a small tank, but I'd put it at least 2 inches. Just keep in
mind that the deeper you make it , the better, but the deeper you make it,
the more space it will take up. I like to make it shallower in the front,
and deeper in the back. Use a nice fine calcium sand.

Some of you had recommended a dsb for lowering nitrates and i said the
lfs told me not to. I said something about nitrogen bubbles and... well
i'm a nubee and was basically talkin' out my bottom and this is what the
lfs said.

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?

Jim

i would go 3 inch, rocks can sink down into the sand so that you dont
lose any cieling room for taller rocks, and a 3 inch DSB in a 45 gal
would be alot more of a beneficial bio load than can be achieved with
a 2inch, and 1 inch is almost useless and WILL get disturbed as your
LFS says, having it deeper allow for better stratifying of the layers
eliminating this problem, and is important to keeping your rock
healthy. if you had a 80 gallon or greated i would go 4-6 inch. you
can push back the front of the DSB to expose a bit more of the glass
as everyone has mentioned only seeing about 2 inches in the front if
that helps, but personally i liek a Deep sand bed, i have a 2.75 inch
in my 29 gal pod.
