First Timer Ready to Fill, Could use some help

[jkoch]

Thanks for the Help.

Can I spinkle in distributed around the pool some of the CYA as is fills along with adding the bleach? As this point I can wade around the pool to mix in the bleach.

thanks,
JK

I wouldn't. CYA is a slow-dissolving acid. I wouldn't want the granules laying on my liner. Just wait until the pool is filled and then you can put the cya into the skimmer. Aim for an initial reading of 30.

Ok. The vinyl pool is filled with 12K gallons of softened well water.

Chlorine: 6.5
CC: 0
PH: 7.5
TA: 280
CYA: 0

I have 1.5 lbs CYA in sock in front of return.

My plan is to add muratic acid and leave the water aereator running to get my Alkalinity Down.

Is this the correct course at this time?

Your help is appreciated very much.

Thank you,
JK

Yes, Your TA is pretty high. It is most likely going to take several cycles of dropping the pH and TA with muriatic acid and then aerating the pH back up, repeat, before you get the TA where you want it.

BTW -- 1.5 lbs. of cya is only gonna take you to about 15ppm. You'll need to try and get it higher than that. 30-50 is a good range for cya.

That is not going to be enough to even test for in 12k gal. Why not take
watermom's advice above and use 3lbs. You can pour the other 1.5 lbs directly into your skimmer if you have one, with the pump running. You will need to get three pounds in there to really have enough in the water to be able to test it.

Edit: Seems watermom and I were posting at the same time! twisted minds think alike!

Thanks, I'll get more CYA. Can I just dump it into my skimmer? I have a sand filter.
Also, Should I leave cover on or off?

[Watermom]

Yes, you can dump it in the skimmer. Just don't backwash for a week to give it plenty of time to dissolve. I usually run my pump 24/7 for the first couple of days after I put cya in the skimmer. I don't think it matters one way or another about the cover.
