Hello,

My pool keeps me humble. I can't say that enough.

We had a pool party last Saturday (9-1); within a day, things went wrong. The pool got cloudy overnight and eats chlorine like nothing I've ever seen. It's never been cloudy like this. The water has more of a "silty" look, as opposed to darkening.

Here are my particulars:

Colored plaster IG 22.5 k gallons
Cartridge filters, pump runs 4 hours/day
No chlorinator nor SWG
Testing is with PS234
Pool gets full sun 10 am to 2pm
We use liquid chlorine to shock, bleach to maintain
Skimmer has a skimmer sock

FC <0.5 (before the party, it was 3.5)
CC 0 (was 0)
Ph stayed at 7.2
Alk stayed at 80
Cal 310 (was 300)
CYA 50 (was 70)
Temp 81 (was 84)

On Tuesday, I cleaned the cartridge filters.

Since Monday, I've added four gallons of 6% bleach and two gallons of 10% liquid chlorine. FC still won't budge.

I also added a quart of Pool Magnet. Usually, this helps, as the autofill lets in small amounts of unfiltered well water.

Also, I added a quart of 60% algecide; algae has, knock on wood, rarely been an issue here; But I did it. No effect.

So, I added two cups of Sparkle Up (filter enhancer, I guess) via the skimmer; no effect

So, I added a quart of Sea Klear clarifier (generic brand); I've never had to use this. And maybe it was $$ down the drain; no effect

Filter basket cleaned daily. Nothing unusual here.

Perhaps I have a combination of problems. But I'm out of ideas. Just keep adding bleach?

Any thoughts much appreciated.

Non-chlorinated cheers from the Sierra Foothills,
Paul
