I was doing some research on chloramines and I found this article about using ascorbic acid to eliminate chlorine and chloramines from tap water. http://www.sfwater.org/Modules/ShowD...ocumentID=6920. It seems that Chloramines are a fairly common method to sanitize water in city water and sewing systems across the US.
I was wondering if it was possible to remove choramines from my pool water, so I took a water sample in a 20 lt. bucket, test it for FC and CC (FC=17 and CC=2), added two grams of ascorbic acid and let it rest for about 12 hours. To my surprise, FC and CC levels showed zero!
I've been struggling with high chloramines levels for several weeks, so I wonder if using some reasonable amount of ascorbic acid would help me to lower my CC level to .5
The article from the San Francisco Water and Sewer System, states that for a medium size bathtub, using 1 gr. will suffice to "clean" chlorine and chloramines out. If I assume that a medium size bathtub can hold about a 100 lts. then I probably could use around 650 gr. for my 65,000 lts. pool. Probably a little bit less to just lower the CC level without exhausting FC.
I know that Ascorbic Acid can be used to eliminate metal stains, so I think it is safe to use on my water and thus worth to try on the CC issue.
Any comments on this?
