Is this true: When FC drops but CC doesn't rise...

[pisymbol]

...the FC was removed from the pool due to sunlight and/or evaporation not from killing algae or other organics.

Is this always true? I ask because I have gone two days straight passing the ONCT but now on my third I see that my FC dropped 1.5 ppm but I have had 0 CC since passing my first ONCT (I mean zero zero...).

You seem to have two threads going. But here's what I said in the other one:

Good to hear your water is clear. Yes, your FC will drop naturally each day based on the amount of sunlight it gets and organic matter it has battled against. Having a CC level of zero is good (ideal in fact) and just means that your water is in a very good place right now. We all lose FC each day differently, so over time we learn how much we expect to replenish each day. Does that help you?
