How much shock should you add for the first time.

[[email protected]]

I am brand new to this site and have read as much as I can. We just opened the pool and have run the filter overnight. The cc is at 0 which I know is normal. I believe the next step is to add shock. How do you know how much to add and how long should we wait before testing the other chemicals?
Thank you in advance.

Welcome to the forum!

When you say shock, most of us here think of the process of "shocking" a pool. Most here use liquid chlorine, sodium hypochlorite, otherwise known as bleach.

Can you post a full set of test results? We can go from there for any advice needed.

FC-0 PH-6.8 and CH100

With a SWG, do you already have your salt at the correct level and also cya at 70 to 80? If so, add enough plain old beach to bring FC to 4 or 5 so your SWG can take over without much strain. A gallon and a half should do you. That PH needs to crawl into the 7.4ish range as well. You list no reading for your TA level. Welcome to the forum and enjoy pool school.

Thank you so much for your help. I don't think my husband gave me the TA level, we thought first step was the shock/bleach. Wish I was a chemistry major!!!!

Welcome to the forum.

Have you found Poolmath on our site that will help you figure your dosages?

Welcome to TFP!

TFPC does require a little reading up front to get there. But, once you do you can look forward to many years of sparkly pool swimming that is troublefree.

We had to fill the pool with well water and the water is too cold for the SWG to give a reading. Any suggestions on what to,put in first?

If you can give a fresh set of test numbers, we will be glad to answer. At least the primary ones...

FC
CC
pH
TA

FC-3
Ph6.8
TA-80
CC-need 5 more degrees to get a reading
CYA-25
CH-200-300

I'm guessing 2 gals of 8.25% bleach, but pool math would answer better

FC needs to be brought up. Also temp won't affect CC reading.
Your CYA is low 30-80 if you are slamming about 30 is good and your PH needs to be 7.2-7.6 slamming 7.2 is good range is low.

Chlorine is always #1 and PH is #2. Everything else can be worked more slowly and managed as you go.

The Chlorine CYA Chart tells you what the min FC level is for your CYA level. Never let the FC level fall below the min or algae will start to grow. Keep PH between 7.5 and 7.8. Everything else can be managed.
