Just moved in, pool beginner

[jonbalfour11]

Hi there, we just moved in and opened the pool. 20k gallon pool, after the shock was done by someone else I started to test the water. Attached are the results. Apart from what the pool math app says to add any other advice would be great. Also is this safe to swim in? What ones are most important for swimming conditions?
Thanks. Any other general advice would be great also.

Jon,

With a CYA of 90 your target FC is 10 to 12 ppm.

Your FC is just slightly high, and that is much better than too low.

Swimming is just fine.

See this chart.. FC/CYA Levels

Thanks,

Keep in mind that the pH test is not valid when FC level is over 10 ppm.

Do you have the ability to drain off some water and refill? Your CYA is a high which means your target FC level is between 10-12 ppm. If you can drain off about 1/3 of the pool volume, your pool will be easier to manage. In the meantime, do your best to test and adjust pH when FC is below 10 ppm.

Yes I do, I will drain 1/3 and refill and retest. Thank you!

This chart is really helpful. Appreciate the response!

Jon,

Since your CYA is 90, and really should be about 40 or so, since you are using Liquid Chlorine and in PA, I would suggest that you drain half the pool.

You can always more CYA if you drain too much.

Thanks,

Jim R.
