I'd also like to know how and why DSB crashes occur.
:notsure: Got me, never heard of the sand crashing, just the tank. best guess could be if all the creatures in the sand died due to bad water or something happening...but that's just a guess.
before suggesting inverts, how much lr will you have?

DSB's take years and years to crash (if it ever does)...if you just have a DSB in your fuge you don't have to worry about it...it won't be big enough to crash.
Basically the theroy is that the DSB is like a balloon with Nutrients and that one day it will get so full it will burst and release tons of stuff into the water..
I have yet to actually see this happen, I run a DSB 6" throughout my 300gal, goin on 2 years now.

I agree and thats the way it was explained to me. You do need sifters. Nass. snails are a great source to do that. They eat anything plus sift the sand to stir. Good to have IMO. I have 50 in my 55 and when I put in my 12 gal.sump/fuge I will have more in there.

a DSB crash would probably be due to a sudden release of hydrogen sulfide (molecule responsible for "rotten egg" and "stink bomb" smell) from the anaerobic portion of the sand bed. this compound is constantly released in small amounts and broken down or diluted, but if the substrate is not stirred, then it may accumulate in pockets that, when suddenly disturbed, would be released as a gas. it will change into sulfur dioxide and sulfuric acid, dissolve in the water, and rapidly poison the tank's inhabitants and acidify the water.
this can be avoided by having invertebrates sifting the sand, preventing bubble formation below the surface of the sand.
