I need some advice about how to maintain Cl levels all week long when we are only at the house where the pool is from Fri night till Sunday night.
For the first 3 weeks, I ran the pump and filters and Cl feeder (Hayward) with Tri-Chlor 24/7. I am still working out how many Cl tabs to put in the feeder on Sunday night. This past Friday, the tabs were gone and the Cl was 0.5 when we got to the house. The water looks great. I added liquid bleach according to the Pool Calculator.
If possible, I'd like to just run the pump/filter 12 hours per day on Monday-Fri. I tried that yesterday. In the morning, the free Cl was 5 and CC 0.5. At 6PM, after a hot day with the pool uncovered and some swimmers, the Cl was 0.5. I covered the pool overnight and ran the pump/feeder from 6P to 6A. This morning the free Cl is 5.
Other numbers: pH 7.2, CYA 40. TA 140.
I also plan to add a few ounces of polyquat-60 every week.
So if I use bleach for the Cl source on the weekends (to reduce the CYA load) and run the pump/feeder with Tri-Chlor 12 hours per day with the pool covered Mon-Fri and the Cl cycles up and down from 5 to 0.5 every day, will that be OK? Are those values Cl high enough to prevent algae? Any other problems I'd run into.
Thanks in advance for your advice and suggestions.
