Tank transfer didn't go well

[fmelindy]

I have done a few tank transfers in my day (moved a lot), but the only time I ever had anything like this happen (and it was exactly like this) was the only time I reused the sand, so naturally I blame the sand. It was a total and complete tank meltdown within a few days of moving, beginning immediately after setting up the new tank. Sorry to hear about your losses, I feel for you.
