Wentdii :-)

I think the temperature change might well have been the problem. I once
had a fluval burn out when we'd gone away for a day. When we got back
there was no water movement and the top of the tank was about 20F
degrees than the bottom. In a tank filled primaily with crypts there
was nothing left but a few stalks. I've seen crypts melt but never
anyrthing this fast.

So temperature is my best guess, but it is still a guess. I can say with
certainty though I've never seen water changes, even frequent large
ones, cause crypts to melt.
