There is also that conventional "expert" advice that states; "if it works don't fix it"!! :joy:
IMO this is rule number one and can override any and or all others.

totally useless and ugly huh????? like this 180 (not mine)

Yes SPS tanks are predominantly BB, but they are alot harder to keep and it just proves you don't need a sand bed......maybe some of you need to check out Steve Wests' site on his setup and he'll explain some stuff, and he'll even state he removes portions of his sandbed over the course of the year and replaces it......And again when you look at his tank it will speak for itself.......Haven't seen any tanks on this site to put up against his so far.........
You should read the above posting of what I said about DSB. My sandbed isn't all that deep and I'm not saying to go for either DSB or BB or SSB, I'm saying it's an option what you go for. I'm not oppose to any one of'em. What I was saying in the quote you stated was that Murph says it needs 3.5+ sandbed inorder for it to work, I'm saying no that's not true since my sandbed is only 2-3" deep depending which part of the tank your looking at and I have nitrogen bubbles all around. :happyfish

i was just wondering will the 3" bed work with any size tank mine is a 75 gal right now i have about 1 3/4" sand bed and dont want to get to deep but want a nice performing filtration,gas exchange and good microphana life
i just cant see burying all my LR under inches of sand and alot less viewing area as well!!
sorry i know this is an old thread

Actually it depends on GRAIN SIZE, but to my knowledge theres is no actuall depth.. What i know is that shallower sandbed than recomended depth(of 4") would simply have less anoxic area equating to somewhat less overall system efficiency. a deeper sanbed will result in complete change to overall sandbed redox resulting in nitrogen storage.(the more the better) . personally i'm a preacher for DSB it has worked for the last ten years for me..but you can have a beautiful succesfull tank with either SS, BB, DSB..and i don't need to see someones tank to prove that.
The only reason i would see going bare bottom is on a Dominated sps tank. cause of the low nutrient required for sps and to avoid occasionally sandstorms..those are the only reasons why the BB could be better than a DSB.
but for me I like to have a piece of the ocean in my house..last time i checked all the Natural reefs of the worlds have sandbeds and theres Dominated sps areas too
as far as removing parts of my sandbed to repleace it with new one
someone explain the reason.. I know Steves tank might speak for it but you're trying to compare it to a 29g or even a 100g

very well said.
and true. a smaller grain size is going to impede flow through itself making anaerobic zones at a shallower depth than a larger grain size will. oolitic is the best for creating anaerobic areas in lower depth. though my favorite would be a 3" layer of oolitic sand covered in another 3" of regular aragonite sand. I am weird I like seeing the anaerobic zones develop in the sand bed, and watching all the worms and stuff move around..... kind of like an ant farm.

However, if these bacteria are disturbed, they will release cyanide, causing a universal extinction.
Bare bottoms are ugly and are totally useless. No one (unless the tank was sterile or an experiment or dealer's tank of some kind) in their right mind would ever have a bare bottom, anywhere. Have a 3'' deep sand in the main tank, and a 6'' deep bed in the sump/refugium.

haha rookie.
