Greetings fellow pool peeps,
It’s been awhile since I’ve needed to use our fabulous TFP forums because, well, my pool has been perfect. Special thanks to this resource :)
Every 5 months or so, I need to add a little CYA to my salt water pool. Our AZ sunshine keeps the levels dwindling and since it’s a salt pool, I don’t use chlorine tablets, which I understand contain CyA.

Today, I popped into Leslie’s to buy CYA. I didn’t plan to add it just yet but want to have it in hand for when it is depleted. With temps warming up and more sunshine, I know this will be in the next few months.

The store rep actually talked me out of ever adding stabilizer/CYA. Instead, she indicated I should be adding shock weekly. If I was doing that, it would also keep my CYA levels correct.

Can you please share your thoughts on this? I’m embarrassed to admit that I’ve never added shock. I’ve never needed to. My SWG keeps my levels in range and I’ve never had any major imbalances or chemistry issues. But, is it recommended to shock every week as part of regular maintenance? Is this the best way to keep up CYA as well, or should I ignore Leslie’s advice and keep doing what I’m doing (adding CYA/stabilizer granules every 5ish months as needed)?

Fyi my current readings:
FC: 7.0
PH: 7.6
TA: 90
CH: 425
CYA: 50
Salt: 3300

Appreciate your advice,
Thank you,
Kim

Smile at the pool store employees. Thank them for their concern. Try your best not to spit up on their floor while you process whatever garbage you were told.

Buy what you walked in for and nothing else. Thank them again. Go about your way.

Kim,

That just shows you how clueless she is about how to care for a saltwater pool. Sigh!!

This is why I say "I'd rather let it dribble down my leg, than go into a Leslie's just to use their bathroom." :mrgreen:

If you maintain your FC and CYA in the proper relationship, you NEVER need to shock your pool.

Thanks,

Jim R.
 
This guy has a saying I like. 👇
😂 Thanks! All I wanted was my CYA and they want to show how smart they are by asking questions. 🙄. Just sell me the product I need and leave me alone. I got this! Instead I walk away questioning myself. Thank goodness I have TFP who has taught me to know better!

Thatreminds me of the time I was told by my uncle that he shocked my aunt’s pool once a week….bc the pool guys told him to, that the chems were “perfect” and that he had been doing it longer than I had my pool and I didn’t know anyting….P.S. her chems were terrible!
