Hello,
I'm just getting started and some of my numbers are not making sense. I've had the pool open for a month and I've had the water clear for about a week. I have the pool at 40K gallons because that's what the pool store said it was.
Last night I wanted to shock it so I added 2 gallons of 12.5% bleach. Using the tf100 test with the dpd powder it took 7 drops to clear the solution prior to adding the bleach so 3.5 FC, and then about an hour and a half after adding the stuff it took 32 drops to clear it so 16 FC. These numbers are way off what the pool calculator says. Am I missing something?
I have the CYA at around 35, but I'm not super confident about that test.
