Hi Everyone. Great to be back after a long, weird winter. Hope and trust everyone is safe, healthy and well.
Just opened the 16x36 inground vinyl (no heater) SWG pool over the weekend.
Water was mostly clear and I was off and running with my Slam. 48 hours later, the water is clearing up really nicely. These are my first results, which are great - other than FC and CYA
FC ~1.0
pH 7.4
Alk 70
CH 65
CYA <30
salt 3200
I realize I am getting very low FC, due to low CYA. But my issue is that I know that when I closed my pool in September that my CYA was 60-70. I know this because of all the data on my TFP pool math app.
I do realize that when I closed the pool, I drained approx 6 inches of water to get below skimmers, and have added that back now with approx 2,000 gallons of fresh water. Ok, I understand the dilution, but that's only approx 10% of my overall volume.
I have added 2 rounds of 2 pounds each CYA, as I understand the best practice is to add it slowly as to not overshoot.
I know I can and will get back to 50-70 CYA and be fine. But I am really curious of the CYA loss over the winter.
