Hi everyone,
We have a new small pool and are a little puzzled by the results we've been getting. Everything was fine until we started up the SWG. We are working with someone and after about a month of the SWG running, he mentioned that there was no chlorine in the pool and so he added chlorine (in addition to the salt, which was 3000-3300 ppm). We went in the pool and there was a very strong smell of chlorine, suits got bleached, hair and skin were dry for days so we knew something was off and got the Taylor K-2006 to test for ourselves. Results were 40-50 ppm FC.
Since then, we've added sodium thiosulfate to no avail, until we shut off the SWG. Once we shut off the SWG, the FC has been coming down with each administration of sodium thiosulfate, though nowhere near as much as it should be coming down according to the instructions for the thio dosing. We've probably added at least 30 tbsp of thio. We've also been consistently getting zero combined chlorine?
Are there any other measurements we should be taking that could help explain why the FC is proving so hard to reduce? and are we correct in assuming that it is in fact the high FC that caused all of those bleach-like effects when we went in the pool? Thanks!
