I opened my pool in mid-April. It was clear with some expected leaves and so forth on the floor. So little that they cleaned up in 20 minutes or so.
At opening:
FC: 4.5
CC: 0
pH: 7.5
TA: 100
CH: 175
CYA: 40
Temp: 53F
ONCL test 2 days later: 0 loss
I didn't see any reason to do anything but add chlorine to bring up to spec and vacuum.
Since then, I've been using about 2-2.5ppm FC per day, which was normal for the middle of last summer, but higher than I expected given the still low sun angle and cool water.
The last couple of days the kids have been in the pool, along with the neighbor kids. I did an ONCL test earlier this week and got a drop of 1.
Yesterday, I lost 3ppm during the day, and ran another ONCL last night and got a 1.5 drop, no CCs measured.
I've measured CYA a half a dozen times and I'm pretty confident in the 40 number.
So does the high usage warrant a SLAM? I should note that my filter socks have been plugging twice daily with pollen, but can't find any good info on how much chlorine pollen will eat up. Robot has been running daily to clean up the pollen on the floor. Pool looks great, but I want to keep it that way.
