I just grabbed a small sample of pool water and measured the following:
FC 0
pH 7.2
TA 20
CH 50
Salt below the scale on the test strips, maybe between 0 and 200.
Borates 10
Temp 47F (measured on my water sample after I brought it back into the house, so the actual pool could be a few degrees colder)
CYA 0
My last measurements from September 2020 were:
FC 6.0
CC 0
pH 8
TA 110
CH 260
Salt 3140
Borates 35
Temp 80F
And I apparently forgot to log CYA late in the season, but it was 60 in July.
What I really don't understand is how TA, CH, and Salt are so low. My closing process involves draining a good bit of water, and the pool has already refilled itself with rain/snow, so I know there's some dilution. But that can't remotely explain salt dropping to nothing.
Are the tests inaccurate if the water is too cold? Should I warm it up to room temp and then test?
