Dawn, You didn't look very closely at the References if you find
little to support the major thesis of the wikipedia explanation of
the Parasite "has no dormant stage in the lifecycle. Ich does not
lie in wait for a weakened fish to infect. However, any facto . . . "
"Obviously the whole thing could have been written by a child . . . " ?
I think not.
There is a lot of good information within the article and it is worth
knowing it is there.
One might check out the references:

Marshall Ostrow's book on Goldfish is also referenced and could be a
good starting point for our Goldfish keeper.
AND TO JOHN's thought:
In 1992, I needed a way to check to see that I had added enough
Thiosulfate to completely remove the Chloramine from my tap water.
The amount of free Chlorine varied a lot month to month. I didn't
want to add too much Thiosulfate because it can drop the pH if used
in excess as it reacts with water and Oxygen releasing H2S and
Sulfuric acid. Just the correct amount is most economical as well.
I found a good formula for OTO Chlorine test solution and doubled the
concentration of the active ingredient. I have offered this for sale
since. I use this liquid test solution to test every batch of change
water I draw. I have checked the water in a lot of fish tanks since
1992 for Chlorine. I have been shocked at how much Chlorine most fish
will tolerate. Even my Killifish will live in 0.01 to 0.05ppm
Chlorine. However, if a tank is empty of fish and has just had a bout
with Ich, a complete water change with tap water would kill the free
swimming stages and the Chloramine could be replaced with a major
water change in a couple of days giving the life cycle of the
Parasite a bath of Chlorine for 7 to 10 days and one would not have
to add any chemicals to the tank to kill the Parasite, just cool it
off and treat with Chlorine remover and restart the Bio-cycle to be
Ich free.
