Hello,
This is our first pool. Inground, 27,300 gallons, Hayward 245 sand filter. It came with the house we just bought. Why does it take so long for the CYA level to show on the test? I used the sock method, it's been 4 days and it's still not showing anything. We started at 0 and added 1.5 lbs per the bottle to raise the level to 30 ppm. Can I assume it's at 30 even though it's not showing yet and start slamming?? Our pH is at 7.4
