I waited more than six months before attempting Amanos again. My second and third batches are now doing fine for me. I'm using the same water source and dosing regimes now as when I lost the first batch. So I still think it was the D.E.
My fish and snails appeared unaffected by the accidental leakage I caused.
That would make sense the D.E. power is tiny to us, but to small animals like shrimp it is a sharp, edgy material that will literally cut their insides. I'm not really sure how small an animal has to be to be affected like that. From what I understand D.E. power is used to kill parasites and other small animals in food grain because they injest it and die. I would vaccum out as much as you can and/or remove the smallest of animals in the tank.
