Just switched to the BBB method from tricolor. For the past week, I've been trying to figure out how much FC my pool loses/day. It looks like it normally is 2ppm/day. However, It's lost 4ppm FC since yesterday. The weather yesterday was cloudy with heavy rain and thunderstorms from yesterday evening through this morning. The rain added about 1.5 inches of water to the pool since yesterday. CC's are still at 0. The FC level is still coming down from shocking that I had to do last week. My question is can heavy rain dilute the water or create a larger FC loss/day than normal? Here's the test results form this morning:
FC-13
CC-0
TC-13
TA - 150
PH - 7.8 (not accurate because of high FC)
CYA - 52
CH - 170
