Silock --

I know a lot about water chemistry and treatment, but I don't know fish.

I'm pretty sure that Olathe disinfects their water with chloramines. Most utilities just use chlorine. Chloramines are a combination of chlorine and ammonia.

A little water chemistry:

Free chlorine is: HOCl plus OCl-. The relative abundance of these will depend on the pH of the water, with more OCl- at higher values of pH.

Ammonia: NH_3 this is toxic to fish and is present at low pH

Ammonium: NH_4^+ this is less/not toxic to fish and predominates at higher values of pH.

Chloramines, sometimes called combined chlorine, made by reacting chlorine and ammonia <-- Olathe uses these
Monochloramine: NH_2Cl
Dichloramine: NHCl_2

So you will need a product that treats both chlorine and ammonia, like htis mentioned.
