Bad Air + Rain = Combined Chlorine?

Normally in mid-summer l get just a trace of CC. Adding R-003 makes just a hint of pink. I think it's the surrounding 40 foot evergreens. They're always shedding bits.

Lately with the wildfires in Canada and bad air quality, thunderstorms that drop over 1/10" seem to be associated with CC spikes up to 1.0 and an extra 2 ppm or so of FC depletion. Keeping FC at upper side of target range brings it back down to in a day or two. I don't remember this in previous summers.

Just asking... Is this pretty normal? Has anyone else seen it? Thanks.

Sounds reasonable. Your water is processing a lot of extra products. This will deplete FC a little quicker than normal, and the FC being consumed transitions to more CCs until oxidized. You're doing well to be vigilant with the chemicals.

I've seen similar this year. Last year was 8 degrees above average here, and a drought with blazing blue skies most days. I didn't blink when it took 60% of the 2X capacity to maintain FC. (Which it stayed on that setting from June to Sept instead of the 3 or 4 usual weeks). I rarely had .5CCs.

This year I have consistant .5 CCs and the 60% has needed to be raised about once a week.

The lowest my FC has been was high target, so I'm about as comfortable as I can be that it's the rain and wildfire combo.
