Sudden mass suicide today Help

OK, what happened?? A few days ago a nano with ONLY a large mushroom rock ( brn/reddish and green stripes shrooms) had a problem.

Nearly all the brownish mushroom, some pretty big, suddenly got real puffy (water?) in the stems. The water perms had been good and stable for months. Some detached and I removed those. I put an Eheim 2213 external filter with floss and a bag of carbon on and changed the floss etc in the tank's back. The grns seemed ok, low but just not expanding as much. So I did an early w/c of a gal or so. This afternoon the tank was quite cloudy and stank. I immediately did a 99% W/C with spare aged sw. I have to leave the wet sand in until I get some more sw, set up a temp holding tank and more sw so I can start all over with the rock. This should be done early this evening.

All I have done recently is trim a few of the brns to prop in another tank which I just started. That was over a week ago. I had checked all the stickies etc to remind me what to do.

So, any ideas folks??? I hate to lose the rock which is about 8" dia. Other than the sand w/ little critters in it and hermit and a couple of small snails thats all that is in the tank. Standard 50/50 compacts.

HELP !!!!!
 
Temps been steady for weeks, 77. Top off w/ the same RO/DI that I've used for a yr. Complete nano overhaul in progress. 100% w/c, cleaning and BB for now. Will be checking the STINKING sand for dead critters. And the rock was above the dsb on raised eggcrate for flow. Arrrrggggg

Thanks....
 
Something must have triggered a wipe in your tank. A temperature spike, change in salinity/pH, new introductions (chemicals, salt, etc) or some kind of animal death can start the event. Better check everything.

You must had quite a bit of die off to make the water stink.
