IIRC, bleach leaves behind some nasty longterm by-products like halomine? and other stuff. Others here have posted the info before. The by-products remain in the fish and are only hazardous to those that eat the fish.
Rainman,
I don't doubt what you say, but that leaves me puzzled. If household bleach is calcium hypochlorite, isn't that the essentially the same thing that city water supplies are treated with? Are we leaving some nasty by-products behind in city water then too? And why does most of the literature I find on it's use as a fish toxicant list it as
nonpersistant in the environment?
