My husband and I can not seem to agree as to how long the pump needs to run and what time of the day is best to do it. I have a 12,000 gallon fiberglass pool in South Louisiana temps are mid 90's ervery day-very little rain and pool is in full sun. I switched to bleach this spring when I discovered I had a CYA level over 150- even with partial emptying ( at least 8 times) it is still around 135- this means that I add bleach- a lot at night and some during the day to keep my cl level around 7-10. My pool water is crystal clear- PH 7.4 TA- 150 Cal- 250

Since I am adding the majority of bleach at around 9PM I have been running the pump 24/7. My husband would like to run it 10-12 hr perday. When would be the best time to run pump?

Thanks for any help. I have enjoyed reading all posts- I check in a couple of times a day. You all are great!
