Hello again TFP!
I cannot find any other posts using Google, or the on-site search regarding this (besides one), so please let me know if I should re-post to a different board here.
I have been using BBB method, learned here to great degree of success. I am very happy using TFP TF100 test kit, and the PoolCalculator App (besides the resetting problem
My girlfriend and her daughter, who live with me and my daughter, are having sinus issues hours after a day in the pool. My daughter and I are NOT having these issues. I am trying to figure out what could be causing the problem.
I have been keeping my FC numbers around 3.0 around swim time (meaning higher when not swimming, generally), although it has gotten down to 1.x for a day and I would fix it right away. I test the pool every day or every other.
CC numbers have varied between 0 and less than .5 the whole summer. usually approximately .25 or less.
PH has been steady at 7.4 or so.
TA has been level, and a little high around 130 or so all summer.
CYA has been kept between 25 and 35.
I have had to be adding water to the pool because of a leak (I suspect in the pipes going to the stairs) which I have somewhat blocked (I will start another thread with this once I nail it down). I don't know if this affects things much. When I tested the fill water for Calcium hardness, I remember it being around 200 or so.
I hate to say this, but last year, we had a Pool Guy, who used the terrible pool tabs etc, .. and my girlfriend and her daughter did NOT have this problem! I can't imaging what would be better last year, when this year there are definitely LESS chemicals in the pool on average.
I use totally plain 8.25% CLorox bleach. Borax rarely. And the pool-store CYA is only the acid itself.
Has anyone else had or heard of issues like this? Any advice or even suspect problems? Anyone even know anyone else with this problem swimming? I am afraid to go back to the pool store with a sample since when I did that last, at the beginning of the summer, it REALLY messed things up!!
Thank you for any input and experiences
