How deep is your Sand Bed? Poll

[danny zubot]

I had more options including bare bottom on the poll but when I posted it excluded a couple of them.

Its interesting to see everone's opinion on sand beds as far as being an
esthetic or functional part of our aquariums. I can't remember which magazine I read this in and my numbers might be slightly off but 75% to 80% of anoxic denitrification occure within the top 3/4 of and inch of the sand bed. I guess I'll be satisfied with my 1.5 to 2 inches.

and for a properly loaded tank that is not overstocked the Live rock and skimming will handle all your de-nitrification needs.

for what it is worth I was one who jumped on the DSB bandwagon as it was all the rage when I was starting up. I started with 6 to 8" depth then about 1 year later I started having algae problems and other problems that I couldn't explain. I moved and removed all the sand except for 1/2 an inch and the problems went away. now the only reason I want to go totally bare bottom is so I can increase the flow in the tank through out the whole tank to aid in detritus removal.

I agree, where is the 0 option? I have quite a bit of flow going through my tank, and quite a bit of it is directed towards the bottom of the tank... I can't imagine what kind of mess I would have if I had a sandbed.

1.5" - 2". Makes my yellow watchman happy & I get more biodiversity.

If you have Gobys in your sand bed I hate to say but chances are you have no bio diversity at all.

At least, not where they're digging.

I had two for a while and they dug in one area and filtered for food in the rest of the tank. nedless to say the sand bed was clean

Well mine must not have read your posts because it mostly eats the frz. mysis, b.s., and blood worms. When I look in the tank after the main lights are out, I can see literally 100s of live mysis, copepods & arthopods crawling around. I seeded the tank with OA's live sand & there's lots of LR & different macroalgae for the "bugs" to hide in. So as long as he doesn't sneak on my computer at night and check out your posts, he'll stay fat & happy & I'll keep my biodiversity Let's here it for illiterate fish
