Frustrated

[staclear]

Thanks Pool Doc for the advise.
I have in ground Gunite,23000 GLs. mesh covered in the winter,was opened last Friday. I use the same process i have done in the last 10 years. Water color was dark green, 1st day I used 4 lb of shocks and a 1/2 gallon of 30% algaecide, 48oz of acid to lower PH, when I dumped the shock in the water, 2 minutes later the white gooey stuff floated to the surface, my thinking was because of heavy Algae, the chlorine shock surfaced to the top.
I switched to liquid bleach, using 24 Qts every day, with that, also the Gooey white stuff surfaced to the top. I used about 4 lbs of filter clarifier which I used for the last 10 years and the pool cleared up by next day, not this time. I repeated the process again while still using bleach, water got blue but no t clear, Yesterday I used 1 Qt of Hydro Floc, 2 minutes later the white Gooey stuff surfaced again, which the label on the Floc bottle suggest this might happen, I ran the pump for an hour, shut it off, 12 hours later I vacuumed to waste, but the white stuff would not go away and remained on top.

PoolDoc, as I mentioned this is the 1st time I experience this kind of problem, the pool used to clear up with in 4 days with pump running 24/7.

I will take your advise and DE test the filter, use liquid bleach, and monitor it for the next week, hopefully the kids can swim next week end.

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?
