SWG %

[ldh_14]

We opened the pool one week ago. I completed a SLAM and met the three exit criteria pool looks great. My question is if I run my filter 12 hours a day 8a-8p, how do I know what percentage to run the SWG? Today I ran it at 65%. I just tested the chlorine after 11 h run time and it’s only at .4 ppm. The salt water generator is from 2022, but I’ve always had a hard time holding chlorine. I know there is a loss daily, but trying to figure out how to maintain. All other numbers are on point other than Cya 40 but working to increase to about 70. But even with CYA, there’s not enough FC. ( CC .2ppm)
Thank you!

Not enough information. What specific SWG do you have? What was the FC at the start of the 11 hours?

Hayward aquarite. I didn’t test this morning.

Aquarite has a number of different cells..what cell do you have?

12 hours at 65% in your pool will add 1.9FC.
That cell is very undersized for your pool.
Do you have automation?
Can you post pictures of your pad?

You should have a Pentair IC-60 or Circupool RJ-60+ for the size of your pool.

I’ve always wondered if it’s the right size… of course on the unit it says it’s up to 40,000. Pool was built in 2022 each year I’m learning more about how to take care of the pool. Always struggled either way maintaining FC.

Run the SWCG at 80% for 16 hours a day. That will add 3 ppm per day. Run longer if needed during mid summer.

@mknauss is spot on. You can run up to 90%, 24hrs/day and make 5.3ppm (Don't run 100% 24/7, not good for the cell).
You just need to match your output (run time and % output) to the need of your pool to maintain FC.

I'd raise your CYA to 60 for now (not higher until you get FC under control).
Raise your FC to the top end of the range for your CYA. Use liquid chlorine Link-->FC/CYA Levels
Then, as Marty indicated, run your SWG at 80% for 16 hours and see if that maintains FC.
If not, up the runtime or output%.
If it rises, lower the runtime or output %.

Thanks for the pics. You have Hayward automation, and that is the largest cell that works with your automation. Don't be afraid to supplement with liquid chlorine if you have a day or two that your SWG can't keep up.
