Yesterday when doing my weekly duty, I was not able to get the water to increase in free chlorine. I am using those sticks that have 4 little pads on them and it usually turns purplr with just a cap or so......4-7 cap fulls later and still no color. The test strips were brand new. Water was changed within 60 days, not a lot of use at all (we were on vacation for 1 1/2 weeks during the 60 days) water looks clear and no odors. Last thing, when I took a soak last night my eyes teared a bit...not sure if this had anything to do with it.
Any tips?
