Time to close the pool! Water temp finally dropped below 60 and looks like we'll start getting some freezing overnight temperatures soon. The pool has been covered for the last month but I've kept the pump running, I did SLAM when I first covered it as I found a bit of algae trying to take hold under the seams of the liner bottom. It took 3 days for the FC to quit dropping then it stayed high for a long time before slowly drifting down to a 6 where it has stayed. Last year I added Polyquat 60 and don't remember for sure what I did with the FC, but I think it was at recommended levels, not shock level. I'm just wondering if I can do both – shock level FC and Polyquat 60 for extra protection? Or if they don't play well together.
I do use a mesh cover so I get fine debris from leaves in the pool. Last summer I didn't have a chance to open in April when it started warming so I peeled back the cover and mixed in some Chlorine. The pool was dirty when opening, but not green and looked perfect after a few vacuums. We get a lot of leaves and tons of rain in the fall and spring and I'd rather deal with a bigger clean-up at opening then mess with it at all in the winter, so the mesh cover worked good.
Current levels are:
Temp: 55'
CYA 40
FC 6
CC 0
PH 7.6
