If my FC gets eaten up during the day (maybe 7 in the morning and 0.5 by evening), but the pool has 0 or 0.5 CC in the evening... am I battling algae or the sun?
I guess what I'm asking is, if it were algae, wouldn't I see higher CC?
For instance, yesterday morning:
Water temp: 89
Air temp yesterday was 94 degrees, lots of sun, pool was open (automatic cover) from 7a-12p and again from 5p-9p. At 9p:
Water temp: 93
When I'm down to 0 or close to 0 on FC, the seams of my liner darken up. The water is consistently very clear.
My only guess is that I'm (still) fighting algae, which FC consumes, then more FC consumes the CC, and when I test, both are cancelled out. Is this off-base?
