Correct, it would help with the nitrates by making those oxygen deprived areas. But, his concern was that such a small square footage of sandbed would eventualy become stagnant because it does not support enough life to clean up the bed. Hence the DSB crashes (for smaller tanks)

In short form: :biggrin:

Nitrate sink yes - but cannot export ditritus properly and becomes saturated causing a ton of issues.

Sand in a bucket for a nitrate sink has been passed around lately. But you need to move the water across the bed fast enough so that it does not let ditritus settle. Otherwise you would have the same issue as the small DSB sized tanks.

I was thinking that if OCDP found that BB was too hard on his YWG.After he cleaned the old sand from his tank,he could add a couple inches of fine sand in an easy to reach part of the tank.Maybe use a dam so it stays where he wants it.If its easy to reach,he can clean it and his YWG will be happy too.Would take some landscaping,maybe more than he wants to do.But its an option.

I dont think this idea is what your looking for, but I tried the faux sand-bed. I absolutely love it so far, couldnt be anything better, I think it throws all the bonuses in one. I have expoxied a sand-bed into the bottom of my 75g tank, and love the results. Basically, you get a sandbed look without all the drawbacks. Syphoning is easy, and it also protects the glass like starboard. The only drawbacks that I have found are that you cannot keep critters that need sand, its not removable, and corraline will grow on it and is hard to get off if you dont want it there. Personaly I like the corraline on it, but if you ever want it off, an urchin would probably do the trick. Also, you could do a high-gloss epoxy finish over it aswell, so that its smooth, but still with the sandbed look.

Just my 2 cents, if anyone wants more info, feel free to ask.
