What is the recommended Salt System for a 22k pool? RJ 60 plus or Core 55 or IC60? Thanks!
Thinking about converting

You will want one that is at least a 50K, 60K is better.
Without automation that can handle a cell, any of those would work. I like the RJ series because the output % are in 5% increments...makes for fewer adjustments during the summer...
What SWG do you have today?

Curious why you say 60 is better than 50. 50 is more than 2x. The bigger, the more expensive cell replacement. I have a 40 for my 17k pool and thinking about going down to 25 for lower cell cost. I only need to set my 40 at 25% for Texas summers, so a 25 at 35-50% should last just as long.

The RJ-45+ is $1379 with 10$ upgrade from the 30.
The RJ-60+ is $1579 with 10$ upgrade from the 45.
The RJ-45 puts out 2 lbs per day, which is 8.3 FC (in 29K pool).
The RJ-60 puts out 3.1 lbs per day, which is 13 FC (same pool).
Assume whatever life you want, I'll choose 10,000 hours, which is 416 days.
416 * 8.3 = 3458 FC
416 * 13 = 5408 FC
1379 / 3458 = $0.40 per FC
1579 / 5408 = $0.29 per FC
The larger cell is cheaper per FC.
You could look at it another way. Assume demand of 3.2.
RJ45 will put out 3.3 (again, 29K pool) at 40%
RJ60 will put out 3.2 (again, 29K pool) at 25%.
Running the cell at a lower percent lowers the runtime and extends the life of the cell. The incremental price of the RJ60 is $200 more (15% more), but you get 2000 more FC (58% more FC).
When you just look at the price of the replacement cell, $694 vs $794, the value is even higher...

Unless either cell dies in 3 years. I think "run time" has less to do with cell life than salt water going through it 24/7. The 7 year warranty is no bargain once you hit year 3 or 4, since you pay the freight. I'm waiting to see if there's a Black Friday sale on cells, but likely going to try the Edge-25 replacement.

If you are not getting more than three years out of a cell, with an OEM cell, I suspect something is wrong with your water chemistry. Salt water going through the cell 24x7 is not going to damage the cell. Running at 100%, 24x7 is the quickest way to kill a cell. Maintaining chemistry that allow scale buildup (positive/high CSI), followed by acid washes is also high on the list. Low pH in the cell can lead to deterioration, not sure how much, but adding borates can help stabilize pH in the cell.

My CSI is always between 0 and -.15 when I check it. Ph is always 7.5-7.7. Pool is clear with no build up other than in cell. I'm thinking maybe my CH above 500 is an issue. Have never run cell above 50%, typically 25-37%.

How much higher than CH 500? 550, 1300?
Run your CSI slightly more negative.

Lower your CH and run your CSI -.3 to -.2. I run mine around -.2 and no buildup after 3 years. @mas985 finds he needs to run ~ -.3 to keep his cell clean.

Speed stir can help. Keep adding drops until the color doesn't change, then subtract the last drop.

I do use speed stir. It turns bluish-purple, but never seems to go blue.

When the color no longer changes, subtract the last drop. The light on the speed stir can alter the color...but it's not about the color, it is about the color change.

Here is the accuracy of Leslies's vs. Taylor. This is with a calibrated machine and a trained operator. No idea what you got there. CH test, Taylor is 11.3x more accurate. Trust your test kit.

Back to the OP's question..... @GHG7F0
If you choose to use a Circupool SWG, the RJ60+ or the RJ45+ will work for your 22000 gallon pool.
With your basic Aqualink Z4 controller, I don't believe the Z4 can control a SWG.
If you had the Aqualink RS, that can control a Jandy SWG.
Most full automation systems require a SWG of the same brand.

Ok sounds good. Usually the RJ60+ will go on Black Friday sale so we will see what thye offer tomorrow. I think last year it was about $1399.

I bought the RJ45+ today for $1345. as I measured my pool and it's actually 18K. It should be here in about a week. Since the water is about 60 or slightly colder I'll wait to use until it warms up in the spring.
