increase CC with rain?

Will lots of rain cause you to have CC's? Just saw that I have .5 of CC. I know thats acceptable, but Im wondering if this is the beginning of algae since we got about 6" of rain on Sat and Sun.
My FC is hovering around 6.

Organic material composed of ammonia based compounds when oxidized by chlorine create CC.

Rain should not create CCs.

Periodically, do an OCLT if you suspect that the fc is insufficient.

Basically, bird guana. Or excrement.
