My pool was closed yesterday morning. Water temp was 58, FC 6.0, CYA 30, and I added 16 ounces of poly 60 thirty minutes prior to closing. I will monitor the water level and will pump out water throughout the winter if needed. My concern is we are having a warm stretch the next week with highs in the 70’s. Actually got to 80 yesterday afternoon and water was at 61 with the warmup. Low this morning was 43. Should I continue to test and add LC or am I overreacting? Weather will soon be highs in the upper 50’s and low’s in the 30’s in a about a week per the future forecast. I do have a mesh cover.
