I use whatever claims to be good agains chloromines-- though I don't know HOW I could recomend one thing over another. The fact is, even WITHOUT using any thing, I wouldn't see any obvious ill-effect. I don't know how to measure a products effectiveness in this matter. Indeed, for a while I actually stopped using these chemicals, until I learned that this isn't a good idea. Even so, like I said, the advantages are not obvious to my eyes.
