. . . .
At that point he said he is not a pool chemical expert . . . .
I'd have to agree with his 2nd statement, but what he said about the other is nonsense.

Here's why: once chlorine, from ANY source -- gas, bleach, cal hypo, trichor, dichlor, SWCG (salt) -- is dissolved in the water, it takes EXACTLY the same form, regardless of where it came from - hypochlorous acid + hypochlorite ion + various chlorinated cyanurates. For his claim to be true, ANY form of chlorine would have to do the damage he claims.

But, as he said, "he is not a pool chemical expert".

In general, when someone tells you they don't know anything about a topic, you should believe them and NOT believe what they say about that topic!
