Interesting.... When you state that FC was 5.0+ this implies that you're utilizing an OTO (yellow) test that only measures to 5 ppm chlorine. I've had occasion to swim in water with greater than 5 ppm Free Chlorine but did not experience any eye irritation. Are the combined chloramines (CCs) testing at .5 ppm or less? The 3300 ppm salt should further alleviate eye irritation because a salt level up to ~7000 ppm is closer to the typical salinity in tears.


Note for the humor-impaired: Do Not Drink cyanuric acid. I was joking.... as was BTDG. Stick to diet soda.
