Hm, interesting, I heard it was the other way around because you're right chloramines are bad!Originally Posted by badflash
Chlorine tablets for pools contain chlorine in the form of Trichloro-S-Triazinetrione, which is C3Cl3N3O3, which is not a monohalogenated species of chlorine; therefore, ascorbic acid would likely work according to the conclusions of the EPA document cited above, and as you have confirmed through observation it does in fact work!
And yes, chlorine does off gas unless it is tightly bound, which is definitely cheaper.
