CC reagent was yellowed, TFP article says that means it's bad. Got new stuff today and a zero CC reading for first time, so I suspect that the old one was causing a false high CC reading. Will inquire on TFP later on.

Had roughly 4.5" of rain, lots of overflow and drain. Removed lots of leaves. Slightly cloudy water, presumably due to all the junk added during rain and not algea, but taking to SLAM level as a precaution.
