I also have a 12000 gallon FB pool. I run my pump 3 times a day: from 8pm to midnight, then from 5am to 7am, then from noon to 2 pm. 8 hrs total.
I add bleach at 8pm, letting it work without the sun to use it up. I check chemistry in the am before work (thus the early start time), and I run the third cycle from noon to 2pm just to move the water around under the solar cover.
I live in the Mojave Desert, it's been over 110 here lately, the pool is in full sun from 8am to 5pm.
My pool is crystal, liquid glass clear.
