New pool and have not added CYA yet so it is at 0. Will be adding 32oz over next few days via sock method to get to 40 I understand this can take a week or more to get the levels up?
Yesterday I tested for FC and it was not even registering, I added 5 cups of 8.75 bleach and tested 30 minutes later, FC was up to 5.
Tested this afternoon for FC and it was back down to 0 in fact the color never even changed.
Today was cool, sun was out full till about 2pm my time, now cloudy.
Pool gets full SOUTH TEXAS sun from 7am till about 5:30 pm when the sun goes behind the house.
Is this normal FC loss for that period of time? How much will the CYA help to prevent this much FC loss?
Thanks for helping me understand this a little better.
