Opened the pool over the weekend:
20X40, 28,500 Gallon Vinyl pool.
Pool was the same green as my lawn, worst opening condition in my 3 years with this pool/house.
Started shock process after some vacuuming to waste, some draining to get CYA and then refill.
So my question is how fast should FC come down? Mine is not dropping as fast as I thought it would considering how green the pool is ?
Here are some numbersMonday night)(Tests with Taylor k-2006/TFTestKit)
FC = 6.5
PH = 7.6
TA = 80
CH = 85
CYA about 35.
With those readings I put in 2 lbs of Cal-Hypo (Low calcium anyway) to get FC back up to 12 - 14
Didn't get a chance to take reading this morning. Pool is green, I know I'm not doing an OFCL test so no real need to check, unless I had time to shock back up to 12 - 14 ppm which I didn't.
Get home from work (took readings about 6pm) and my FC is still at 8ppm !! (Live in Central NJ and it hasn't been that sunny for past 2 days)
I was assuming my FC would be close to zero with how green my pool is by the time I got home? I would have thought my chlorine would be getting eaten up like crazy?
Pool is still green.
Added 1.25 gallons of 12.5% chlorine to bring FC back up to 12 - 14.
Thanks in advance
