I have checked all pool chemistry values (TF-100) diligently for the last week, since we filled our new pool..
Initially, the values were all over the place, but after balancing, I am noticing the following:
For the last 2 days, the values of FC = 6, CC = 0 & pH = 7.5 are consistantly constant throughout the day.
We had kids swim in the water prior to that and I had to add some bleach & acid to bring the levels above.. but since then I have not added anything to the pool.
It has been cloudy for the last couple of days (a rarity in PHX) - maybe this is why FC is constant?
