It's getting really cold here in CO and it's time to close the pool down. We had a dusting of snow already. I tested the water and was wondering how it looks.
above ground, about 10,000 gallons, swg, 1600 gph sand filter
alk = 80
fc = 9
cc= 0
ph = 7.5
cal = 60
cya = 40

This is our first year and I'm not sure that process and could use some help. I read to use some 60% polyquat algaecide, can I get that at walmart? Does anything need adjusted? Thanks much
