I have a RO setup that I use for drinking as well as brew water. I use a pressure tank that holds 7 gallons to help with brew days, but ordinarily there is not a lot of water turnover. That seems to lead to a bit of water contamination over time, which I can eventually taste. It's kind of a moldy taste. I had been sanitizing with Star San, but that didn't work very well the last time and the taste came back within a month.
So this time I picked up some Io Star, and sanitized the lines and pressure tank with that (about 1-2 tbsp/5 gallons) I probably let it sit for 30-45 minutes. Then washed it out of the system 4-5 times. The water still has a medicinal-iodine taste to it, although the moldy taste was essentially annihilated.
Any suggestions?
I've read that sodium thiosulfate can remove iodine from water. I don't want to ingest any more chemicals than necessary to get the job done.
