A lot of us are. I use Campden tablets (K2S2O5) to de-chlorinate my tap water.
Yeah, I do the same but for the anti-chloramine benefit - not as oxidation reduction additive. I was really asking about anti-oxidation usage of Campden tablets.
Since we're talking about it now, I was also wondering if there were ppm recommendations for this also - the "casual" recommendation of a single Campden tablet de-chlorinates 20 gallons (http://www.howtobrew.com/section1/chapter4-1.html
) seems to leave a lot of room for improving dosing accuracy.
Hey! Maybe John & Colin can discuss this in their water book?!??!?
