I have been slamming my pool for the past week, and am seeing a VAST improvement in the water clarity...
My question has to do with the CYA level... I don't see ANY CYA in my pool, however after a full day of sun, my FC only dropped 5ppm from 16 at 6am to 10.5 at 6pm.
Without any measerable CYA, is this a normal drop? I expected the FC to be a LOT lower this evening.
levels at 6pm
FC 10.5

TA 80
PH 7.2
CYA <20
I have had 0 drop in FC in the overnight drop test for the past 3 nights straight.
