Frustrated

[PoolDoc]

Thanks, Richard.

StaClear, pools vary from year to year for all sorts of reasons. Even if it never happened before, it happened this year. If I was at pool side at your home, and could check everything out, I might give more specific advice. But, I'm not there, so I can't.

Most likely, it's going to take awhile to clear things up. Just follow the list, and report what you find.

Best wishes!

40% Improvement form yesterday, the water is blue and clear in the shallow end (4ft deep).
with water chemistry as follow:
FAC-3
PH- 7.2
TA- 110
CH- 180
CYA- 40

The problem now is, can not hold chlorine every day I pour 24 Qt of 6% Bleach at night time, 12 hours later FAC reading is .5, what can be done/ Should I raise CYA level?

No. Your cya is great at 40. You need to try to add chlorine more often instead of waiting 12 hours between doses. A pain, I know. But, necessary if you are going to defeat this problem. The more times a day you can test and shock it back up, the quicker you are gonna clear this pool. Glad to hear of the big improvement. Keep at it.

It is normal for chlorine to be consumed as it clears the pool since it is getting used up breaking down what you currently see is making the pool cloudy. Even after it gets fairly clear, you may still have a higher-than-normal chlorine demand, but this should return to normal in a day or two after it's clear.

The key is to MAINTAIN the shock level of chlorine until three things happen: 1) the pool is crystal clear, 2) the overnight FC drop is <= 1 ppm and 3) the CC measures <= 0.5 ppm.

Slowly but surely!!! The color of water is improving . I'm shocking it twice a day, thanks for all of your help, the only thing remain is to figure out how to hold chlorine in the water longer.
CYA is steady at 40, PH 7.4- with $20 of bleach every day, is getting too costly!!!! any idea what to do beside patience?

[staclear]

Crystal clear!!!! after 10 days, a lot of bleach, a couple handful of DE in the sand filter, pump running 24/7. This forum taught me a lot. What helped my pool the most, NOT to backwash frequently and let the filter do it's job.
