Well, Ouch! too.
The recent stir up of my DSB lead to more problems. I managed to blown away most of the cyno's, but today, after the water cleared up a bit, I find most of my softies melted. I lost a yellow leather, pink colt, toadstool, pink tree coral, 2 cleaner shrimps, & a 6" gigas clam.
Do I think the mass death is due to the detritus being stirred up? Maybe.
Do I think the death is due to the H2S concentration surged way up high? Definetely.
Although I do not have a kit to measure the concentration of H2S in my tank, but I would bet the concentration right now is still high. Other than rotten egg smell from my sump, there is also huge amount of foams on top of my sump. I believe its mainly the release of H2S (which is the direct by-product of a undisturbed DSB) that killed my tank.
I doubt the O2 deficiency plays a factor here as I did not loose any fish. All tangs are doing Very well and is still eating like pigs (the Cheveron that I added before the weekend is doing very well, in fact).
So, james, back to your comment, I disagree your disagree of my disagree and Rick's disagree that O2 concentration and the roll of denitrification does not play a significant roll. I still believe it does, and the culprit may be the concentration of H2S.
