Clear, but no chlorine???

Only need to vacuum if there's stuff to clean up. You should, however, brush floor and walls. How much bleach did you use yesterday?

I didn't add any bleach yesterday. The FC was 33 at 7am and went down to 30 in the afternoon and and stayed @ 30 all night.

It's good to hear that the chlorine demand has subsided. Now to get a few sunny days to clear the CC.

OK- so, as long as the pool is holding chlorine, the sunlight will lower the CC level? Sunlight lowers CC?

We are on the cusp of a severe thunderstorm with high winds, hail etc. No sun today unfortunately.

I should continue testing, right? If FC is at 30 now, at what number should I add more bleach?

[BigDave]

Chlorine and sunlight sould work together to clear CC. But remember, we still don't know what caused the chlorine demand and the CC in the first place, so we're following a general rule and not working to remove a known contaminant.
Yep, keep testing in the evening and morning - doesn't sound like there's any reason to test more often than that. Since each jug adds about 5ppm FC to your pool, add another jug when the FC gets to 28-30ppm.
