High free chlorine

[Jsf721]

Went out today to take a look at the pool and do my water testing below are my results which I did log in pool math. I turned my generator down from 60% to 50% but I’m not sure that that’s even low enough, the chlorine was at 25 which is the highest it’s ever been but I’m new to the saltwater generator and I started out at 60%. And I’m not on site to monitor daily I’m not sure if the other test results are accurate due to the extremely high chlorine. My pool company added 1 gallon of muriatic acid this morning to lower the pH. I’m not confident that it’s been fully mixed as he only put it in about an hour ago.

Looking for suggestions on saltwater generator settings as the next time I’ll be out at this pool will be the weekend of May 17

Thanks very much for any recommendations

At a FC of 25 ppm, then the pH test is invalid and no adjustments should be made.

Be ware of using pool company testing for any chemical adjustments.

Your RJ-60 will make 2ppm of chlorine a day running pump 24x7 and 20% output.
It really depends on the pool, how much it will use on a daily basis.
Is your CYA really 90?
Do this test starting at #8:

CYA - Cyanuric Acid Test

Cyanuric acid (CYA) is the chemical name for the product commonly called “pool water stabilizer” … Read more…

Do you use a solar cover?
Does the pool get full sunlight?
We can make a general recommendation knowing these things to get you to the 17th.

I do all my testing with the TF pro kit with salt.

My sonar acid is 90 if not 100. I never rely on Lesly‘s testing which is why I bought my own test kit and to prove to myself that there was bad as this board said they were years ago. I took the same water sample to three Lesly‘s and got three remarkedly different test results. At that point, I started drinking the Kool-Aid around here.

My pump is running 10 hours a day currently it was set at 60% and I dropped it to 50% looking for feedback on if that’s the proper percentage to leave it at I would like my free chlorine to drop into the green zone for a 90 CYA.

My pool gets full sun for about five hours a day picture taken at 3:15 and then it slowly goes out of the sun. I do not have a cover of any type. Water temperature is a little over 60°.

Do the test linked, start at #8.

I'm still losing / producing about 2 FC a day nearby in full sun. It's going to be mostly cloudy or raining until the 13th so you'll be losing less than 2 FC a day for most of the stretch until you're back again.

If its running 24/7 then 10% is probably good to let it drift down while still adding a little

Ok that’s was something I never did before. I got 40 on the tube so x 2 is 80.

Since the pump is running 10 hours a day I set it a 25% and see how that does. Thanks for the advice.

Awsome. Any equivalent maths works.

Are you familiar with letting poolmath do the calcs for you ? (Upper left menu : effects of adding, swg ).

You can chose FC created, pump hours or %, once you select your model and your volume. If you enter 2 it will give you the 3rd, for example 10 hours at 25% will make X.X FC. Then you can mess with them all to find however you want to set it for next week. Maybe you want it to make 1.5 FC a day. Maybe you want it to do so in a 10 hour window. Poolmath is the bees knees here.

I am not but I will check it out.
