I think DSB dont just "crash". If there is a trematic problem in your tank where there is major die off from overheating or bad PH spike from a kalk mishap or whatnot the sandbed fuana might die off as well.
But IME sand beds dont just "crash", as long as you dont have a plenum!
J/K about the last comment dont need that debate.
Seriously though sand beds are very stable of course stirring the deep sand bed down through it heavily would cause a die off of the anarobotic (sp?) bacteria.
Hope this is what you are looking for!

Ya, I agree with Ben. I don't think DSBs crash so much as they gradually decline, or so it's said. However, I've had a DSB going for 8+ years and only recently (last 2-3 months) am I experience more algae growth. But I don't think it has much to do with the age of the DSB, but rather a function of 2 fish and a large soft coral having died in my tank recently.
IME, DSB is the easiest way to keep your tank condition stable and to eliminate nitrogenous waste from your tank. I have used everything in the last 25 years of marine aquarium keeping. From under grave filter, to reverse under gravel with canister filter, fluidized filter, wet day, live rock/protein skimmer, coarse thick bed, ect. A good DSB is full of life, very stable. If something happens and causes a die off of significant percentage of the life in the sand bed, then this can cascade and can really kill your tank. I am setting up another DSB combine with skimmer and a deep sand macroalgae refugium. This is the easiest way to maintain a thriving reef in my experience.

Ok In my tank I have about a 1 1/2 inch sand bed in there and about 60 or 70 lbs LR. ONe of the fish I have is a sandsifte goby that I dont wanna get rid of so I was thinking of setting up a 2 1/2 gal refugium with a dsb and macro. then if something happens to the refugium dsb I can yank it from my setup without touching the other parts. Good Idea or no??
Yes DSB's do crash. Those that say they don't have not read or talked to those that have had them crash. Most DSB’s decline at a steady rate. Some last a couple of years, some last a lot longer. It all depends on the maintenance that the aquarist wants to or willing to do. Some when the oxygen level is not high enough, say during a power outage or at night for some reason, actually crash and crash hard. DSB's require lots of o2 exchange at the water column level to work.
For me, I don’t like DSB’s and think they are over suggested :roll: and are poor substitutes for those that don’t want to take of care basic system maintenance.

got any proof for any of this???

Just wondering

well off course!!! Everything can crash in the absence of Oxygen.
Actually properly set up DSB are used to make a place for anarobotic bacteria. In other words bacteria that need a devoid area of o2 to live. O2 is what would cause the crash of the bacteria in the sand bed. When you set up a DSB with the right combo of sand grains, IMO Oolite and sp. sea floor grade sand 74%-25%, you create two zones in the first 1/4-3/4" it has O2 in it causing 02 loving bacteria to grow there. This is the bacteria that turns Ammonia to Nitrite to Nitrate. Then in the deeper parts of the sand bed very very low levels of 02 exist causing the anarobotic bacteria to grow which in a nutshell turns the free nitrate to Nitrogenous gas, which exits your tank. So low 02 levels in a DSB are what you are looking for and won’t cause a crash.
If you think this is wrong somehow explain!

Very succinctly put, Ben. I would like to suggest further reading on DSB's -- "The Natural Marine Aquarium-Reef Invertebrates". There is also a good deal of very good information on refugia methodologies as well, and from my own communications the information contained within is gleaned from many, many years of experience, not just of the authors, but from others as well.
However, I would like to point out again that this is an imperfect science, and is as much an art as well.

Seems a bit small for a dsb. Why do you want to add it? Are you having problems in your tank?
Me, I've got a dsb in the main tank and the sump.
On the recent spate of 'dsb bad': I think any system can crash for any number of reasons. To point to a dsb as the reason, I believe, is scapegoating.
Some macros sound like a good idea to uptake nutrients, and the extra dsb is nice for the same reasons, but if you reason is to get sandbed fauna, then you should only do it if you like to look at sanbed fauna.
I don't think you NEED any of it (unless you are having a problem). So, sure they sound like a good idea, but so does your getting a 2000 gallon system with all the bells and whistles! :mrgreen:
