What NOT to do...

[Bleach=Chlorine?]

One good thing about having the pool directly out back... makes it hard to ignore testing duties. I too found after this weekend of hard rain that I had 0FC but 0 CC... dosed it up yesterday.

Mea Culpa! I've done it too--let the solar cover sit too long without looking underneath.

I got to thinking about that today before I even read your post...wondering if leaving the cover on for almost a week without letting the pool "breathe" exacerbated the problem since I did still have a little chlorine left in the pool and have never had a CC reading this year...???

Just a quick update...

After I got home last night (and it was almost night...8 PM), I uncovered the pool and the water was clear but there was a very slight film of algae all over the bottom and sides. I gave it a quick but thorough vacuum & brushing and added more bleach and some Borax (pH was 7.2, but I would like it to be 7.5). When I was done the water was no longer clear...it was a very cloudy green again since I'd stirred up all the algae. .

I took the cover off today and my water was CRYSTAL CLEAR. Filter pressure was up over 30 again though, but a quick backwashing took care of that (not surprising since there was so much algae in the water last night. My water hasn't looked this good since the day we filled it! I can clearly see the "x" on the heads of the screws on my main drain (8' deep end)!

BLEACH WORKS!
