I just opened my pool. Of course no chlorine so I shocked with bleach. Only to 5ppm, but it looks good and no CC. With the dilution from adding snow and rain and refilling, I figured my salt would be down, but I was amazed that my SWG says 2400. I haven't added CYA yet (planning to soon as I understand that last years will all be gone) so I assume its 0; it was 70 last year.
Here are my numbers after 24 hours, which seem OK according to trouble free pool:
pH FC/CC TA CH Temp
7.4 2.0/0 90 120 64
I thought I'd get a pool salt check before adding in the salt, which agreed 2400.
Pool Calc says 84 lbs salt, Pool store says 160 lbs, but try 80 lbs first, as that might do it.
But Pool store also said that Calcium is too low, add 7 kg Hy-cal. I notice my CH is 120 (was all year as well) Settings for pool calculator say "traditional pool", which raises CH recommendation to 200-400 vs trouble free pool settings of 50-300. It's only $10 worth of Calcium and my wife already bought it, - should I add it?
Also, Pool store says "Phosphates 1000, should be 500" - recommend 1.5 litres of Phos-Free - I don't know how to relate this to the pool calculator.
