Pool Closing Concerns

[Watermom]

There is a stickied thread that talks about closing an AG pool. If you haven't already done so, it would probably be helpful for you to read it.

With a CYA of 70, I would take the chlorine up before you close the pool. Take a look at the Best Guess Chlorine Chart in my signature below. A FC of 4.8 is flirting with algae with that CYA level. (By the way, just use a 10ml sample instead of a 25ml sample when you test. It will save on your reagents.)

thank you, I am feeling less stressed about raising the chlorine level. Between last night and tonight I raised my chlorine level to 9.5. By looking at the best guess chart I see I can bring level up to 20. I have the polyquat ready to go, but my pump is a cartridge filter and it has no recirculate option. Instead of running the pump, can I run my pool rover?, its self propelled and will aerate the water while it vacuums. Is this an option? They way I understand the best guess chart, 5-10 should be my chlorine levels, up to 20 is shock level. I want you folks to know how much you are appreciated. Thank you again. YvonneSEU

I think it would be ok to run your rover. You are understanding the Best Guess chart correctly.

And, you are welcome!

Thank you again. I will go forward with pool closing now. Thank you again.
