Hello all. I discovered this site about a month ago when I opened up my pool for the first time since taking ownership of our house. I've read all through pool school, as well as many threads in this forum, and feel pretty well versed on the TFP method. My pool looks perfect, and mostly is. But I like to swim underwater with my eyes open, and after less than half an hour of swimming in my pool, my eyes are red and dry.
My pool had high CYA (160ppm) so I drained and refilled until now down to 45. Though early on I thought my CYA was 60, do to not having the best light while performing the test. Have since redone and confirmed lower, 45 for CYA. So when I opened the pool, I slammed it at the 60 CYA level, then once I passed the OCLT, I kept it at the levels for 60 CYA pool. I noticed my eyes hurting, and thought maybe I had my free chlorine level too high. I retested my CYA and found it was 45, and have been keeping my chlorine levels a little lower, about 5.5ppm. This evening, before sundown, it was down to 4ppm and I swam and still had red eyes afterwards.
I've searched on this, and the only other thread I can find about red eyes is some person who winterized with RV antifreeze. I don't think my pool has ever had that done to it, I certainly didn't. I suppose it's possible that I'm just ultrasensitive to chlorine, but I'm wondering if anyone else has any ideas. Could my relatively high TA have something to do with it? Or is some amount of dry skin/eye redness normal? My numbers are below
