Re: Water change=dead fish.....
It's likely your water contains chloramine (currently mandated nearly
everywhere by the EPA). Using the wrong dechlor product can release a burst
of ammonia. If the pH is much above 7, that's deadly in nearly any
measurable amount. You should never, ever be able to detect the slightest
trace of ammonia.
There are all kinds of other possible causes, but barring any real disease
symptoms, I'd bet it was because you didn't use "Amquel" or "Prime" or "Ammo
Lock 2" or equivalent, and they died from ammonia poisoning from such a
large percentage change.

"DEMOCRACY" is two wolves and a lamb voting on lunch.
"LIBERTY" is a well-armed lamb denying enforcement of the vote.
