In-Ground Gunnite Pool
POOL size: 40,000 gal
Filter: Hayward, DE-4800
I am in central Jersey.
I will have my pool closing/winterization next week by a company. I am however taking care of the chemistry.
I am not understanding a few things:
1. What does it mean by bringing the pool to Shock Level FC?
2. Can I Shock the pool and throw in algaecide at about the same time? (There is no algae in the pool right now)
3. Last Sunday evening, the FC level was 0.5, I used 1lb shock (which according to the label treats about 16k gal., my pool is 40K gal.), ran the filter for 6 hrs, when I tested the water next day the FC was at 5.0, Is this normal? I want to use another 1lb of shock before the pool is closed next week. Should I do that?
