TF-100 arrived yesterday - First set of numbers in and pool is cloudy

[cp3]

My pool went from green and full of algae to cloudy sky blue to now deep blue but still cloudy.

Initially put about 6-7 gallons of 10% bleach and then it was cloudy so I put in some old clarifier which made it even cloudier - white small particles could be seen.

Bought a new filter on Monday and been cleaned a ton of grey slime for a few days. Now I'm cleaning the filter and no more slime just dirt. I can see about a foot into the pool but then it is cloudy.

Test results from yesterday evening. Going to check again shortly.

FC 1
CC .5
PH 7.8
TA 260
CYA 0

Are these numbers possible? Goal is to clear up the cloudiness but don't know where to go from here.

 

[jblizzle]

Those numbers are certainly possible. And please don't get impatient and start using potions like clarifiers at this point.

Here's what I would suggest. Step one add 10 PPM of FC and recheck the FC and CC after 15 minutes and report back.

Depending on the results of the above, you would then add 30 PPM of cya and follow the slam process to clear up the pool.

This might be a dumb question and I'm new to pools.

I only have liquid chlorine. How would I know how much 10ppm is?

 

[cp3]

Found this chart. My pool is roughly 8k gallons. Need to check the chlorine type I have but fairly certain I have calcium hypo.

 

[jblizzle]

Use PoolMath which is a link at the top of the forum.

Bleach is sodium hypochloride not calcium hypochloride.

Use poolmath. Plug in your volume at the top, select the strength of the bleach, your now FC and your target of 10 and boom! ppm to ounces.

Bleach is sodium hypochlorite. Cal-hypo is a granular powder.

 

[cp3]

You guys are great. I have 10% sodium hypo. Adding Now and will retest

 

[cp3]

Just retested and my FC is 5

 

[duraleigh]

You're good to go! Start the SLAM procedure.

There is an article in pool school that will tell you how. Follow that article step by step. ask questions along the way. You are not far from a sparkling pool.

You will first need to put in a Dose of CYA to equal 30 ppm (use poolMath....we'll help) and then we'll need to put your FC up around 12 ppm.

Do you have CYA on hand? Do you have lot's more chlorine?

 

[ship of fools]

You need to get stabilzer/cya in there so your chlorine doesn't burn off. Go to 30 ppm

 

[cp3]

Added 1lb of powder (granular) stabilizer. I have 2 more gallons of 10% sodium hypo but can pick up more.

Can I test CYA right away or give it a few minutes to let it work around?

 

[jblizzle]

You should be putting the cya in a sock and allowing it to slowly dissolve in front of a return jet.

 

[BattleOfYakima]

if you just poured the CYA into the pool, BRUSH BRUSH BRUSH with soft bristled brush (or gently with vac head if you don't have a brush) until it is all dissolved. Don't let it sit on the liner, it's a weak acid, but still an acid, not to mention, you want it dissolved.

 

[cp3]

I poured it directly into the skimmer.

 

[cp3]

I'll test tomorrow again as I have a wedding to get ready for tonight.

Should I test CYA tomorrow morning or should I wait longer to get a better reading?

Pump/filter will be running non-stop.

 

[jblizzle]

Hard to say. If you just dump the CYA into the skimmer so it got sucked into the pump it is possible it might take up to a week for it dissolve and show up in the test. That is why we do not recommend adding in that method.

 

[ship of fools]

As others have said brush the pool and run the pump. Don't add any more and dose your pool as if all of the cya you added is in the pool

 

[ship of fools]

Also do the math to get you up to 14 or 15 and add it before your wedding. That should keep you at 12 until the morning then add more. Follow that routine until you're clear. When the pressure goes up by 25% backwash / clean your filter.
