It seems like I am losing a lot of chlorine in short amount of time. I tested added chlorine Thursday evening ~5pm and level was ~10.5ppm. This morning I tested @ ~11am and the FC was 2.5. A loss of 8ppm in a full day of sun and 2 nights. My pool is not leaking; turned automated filler off for a few days before this and level stayed normal after 2 relatively warm-sunny days. I tested CC and color remainded clear after adding the R-003 reagent.
Any thoughts. Could my volume be off? But then again, is 1-2k gallons going to break the bank here?
