I have an odd "problem" (??? not sure if I can call it that). After I cleared up my medium green water at opening (rather easily I may add), I was focused on lowering the ALK and raising the PH. Once that was in balance (good enough....150 alk and 7.4 PH), I chlorinated up to 4-5ppm, swept and ran the filter/fountain for a few days. Then, I shut off filter and covered with solar cover to try and warm the 60 degree water up. Almost 3 days went by (of non-stop baseball games) and I realized I neglected my pool. No filtering or chlorine for 3 days. I tested this morning and chlorine still 5ppm. How is it that it didn't budge?? Lack of sunshine? 60 degree water? I guess I'm not complaining, but I'm confused. My CYA is around 60 according the the pool store. Here are all my numbers:

TC - 5ppm
PH - 7.4
ALK - 150
TH - 450
CYA - 60
water temp - 62

15x30 AG 10,500 gallons, vinyl liner

Is chlorine at 5ppm too high to swim in if the temp warms up? Based on a CYA of 60, shouldn't my chlorine always stay around 5ppm?

Thanks everyone! I'm learning!
