returned and pool completely cloudy

[duraleigh]

Poolhelp,

John's advice on pH is good to follow.

I am assuming you cannot test for CC's. You would be wise to get a kit that will do that.

I would test at dusk this evening and add enough Cl to bring it back up to 15-17 if your pool is vinyl...25ppm if your pool is plaster or Fibreglas.....calculate and add Cl accurately.

Test again tomorrow AM...before the Sun hits it too hard. If you've lost more than maybe 1-2ppm, you are still killing organics in your pool.

The solution to that is to keep adding Cl back up to those levels above over and over 'til the pool clears. A struggle for now, but you'll find it well worth the effort.

Cloudiness in pools can be from a variety of causes but your test results indicate that Chlorine is the answer to clearing your pool.

Remember to lower the pH....I'd shoot for 7.2

thanks so much. i do have a vinyl liner, 20,000 gallons with heater.
i have a bioguard product that is for decreasing ph that i have had before i found this forum. is that okay to use that decreaser to lower my ph or should get and only use the muriatic acid to lower it?

It's their packaging of dry acid. Go ahead and use it.

should have asked this question in my last post...
does it matter how i add this two products??
do i add the ph decreaser first and then the bleach?
do i need to wait any length of time in between adding these two products?

For the dry acid, it's probably best to either add it through the skimmer with the pump running--or if it were my pool, I would probably dissolve it in water first, then pour it slowly in front of the return to let it help dispurse the acid. That's how I add my bleach, too....and it doesn't matter which order you add them in, and you don't need to wait any length of time between additions. Once the chems are in the water, they're fine.

I wouldn't pour them in simultaneously, however, if you add each to the return stream, allowing each to spread out a bit, you can do one pretty much right after the other.

Generally, we say fix pH first.

thanks. i will do what you guys have told me as soon as i get home from work and i will post my results tomorrow morning. please stay with me and help guide me to get this mess cleared up. thanks again!!

YEAH!!! Improvement!!! I can barely barely see the drain...but i can see it!!! the entire pool is still cloudy but improved! last night i added one pound of the ph decreaser as advised and 3 of the 3/4 bleach to bring back to 15.
Results this morning...
cl-12
ta-180
cya-50 (i didn't check again, but this is where it has been staying)
ph- back up to 7.8 could be a little higher
before i left for work, i added another pound of the ph decreaser and 2 of the 3/4 bleach to get back to 15. this is ultra beach that i have been adding.
am i doing right?
do i continue to hold it at 15 until it completely clears?
do i continue to try to lower ph too if it continues to climb?
please please advise. i am so thankful to each of you that is helping me!
