What do you think of a reverse undergravel with a deep sandbed?I'm getting a headache and don't know why we all don't run reverse undergravel filters.
I've had a dsb this time for 9 years, sometimes clean 1/4 of top layer about 1" in a 60 gal show tank I have never had any problems caused by dsb. Also my sand came from Jacksonville beach, Same tank using St. Petersburg beach sand ran 5 years no problem. Some fish i have move sand, I move it back once in awhile, they just move it again, maybe this helps not sure. I've only lost fish & Inverts one being a Huge long tentacle anomie 10" or more due to ick breakout from new coral beauty, I didn't catch it soon enough. All but two out of 8 fish and 4 shrimp died. The survivors still living now about 12 years. I am the one to never recover and only added 1 fish since loss.I can't tell you how many times I've read warnings on discussion boards about deep sand beds (DSBs) risking a tank crash if the anaerobic layer is disturbed and toxic gases are released. I am beginning to think this is a myth. There is no good evidence for it and very few first-person testimonials. On the other hand, DSB enthusiasts note that they've had them for years or decades with no problem (and lots of benefits, including stabilizing alkalinity).
Are there credible first person accounts of DSBs poisoning their tanks?
If/when you do the DSB, it is important that you do it correctly and I am enclosing a link to brief article. Pay special attention the what he says about the size of the substrate. http://www.reefkeeping.com/issues/2003-06/rs/feature/index.phpHi.
Do you think it is feasible to go from BareBottom to DSB in a running tank (more than two years running BB), and if it is, what advice would you give me?
I live next to Mediterranean Sea (5 mins from my house) , where the salinity level is 38ppt, i read that some of you seed the sand with natural beach sand to get a biological vector, do you think that with this salinity level difference will be useful ?
thanks in advance.

Do the micro fauna really reproduce fast enough? I'd like a goby but I also know that if there's no life in the dsb then what's the pointI have a whole bunch of leopard wrasses that cannot disturb the sandbed enough to notice. Conchs eat worms in the sand, among other things, but there is always enough for them to repopulate to equilibrium. Cucumbers eat some microfauna as well... but, again, they can repopulate with ease.
