Replacing the SJ-20 Classic cell will allow your salt chlorine generator to begin chlorinating again if your old SJ-20 Classic salt cell has been depleted.

Sizing:
When replacing your Circupool SJ-20 Classic salt cell, take this opportunity to make sure it is sized correctly. Sizing your salt cell properly is key to making sure you will not need to supplement with additional chlorine or shock your pool, and also extends the lifespan of your cell.
The industry recommends using a salt cell with a max capacity of 1.5-2 times the actual size of your pool (more is better). The Circupool SJ-20 Classic salt chlorine generator is manufacturer rated for a maximum capacity of 20,000 gallons.
Compatibility:
This replacement salt cell for the Circupool SJ-20 Classic is 100% compatible with original SJ-20 Classic systems (no software/firmware issues). The Circupool SJ-20 cell has the same length, threading, and cable connection for direct replacement.
Not compatible with next-generation SJ-A models.
To get the most life out of your salt cell and to keep your pool running without unexpected interruptions, make sure it is sized correctly, maintain correct water balance, and be sure and inspect your cell at least every 3 months for leaks, debris, and calcium scale. Be sure to follow instructions in the product manual and clean the cell as often as the system indicates.
General FAQ
If your salt cell needs to be replaced, you probably have a problem with low chlorine, but if your chlorine level is a problem then the cell is only one of several possible issues, notably including excessive chlorine demand. Essentially, you have either a system problem or a water problem.
System problems will generally reveal themselves with error messages or warning lights on the control module. The typical indications of the cell needing replacement will be one or both of the following: Low Salt warnings that are present with correct salinity and Check/Clean Cell warnings that display when the cell is verifiably clean.
If you are referring to buying the same brand, there’s no question that the original OEM salt cell is exactly what your system was designed to use. However, commonly there are aftermarket replacement cells available which fit into place and operate quite satisfactorily. It is your prerogative to employ one of these aftermarket replacements if you are satisfied with the specifications, price warranty, and reported compatibility.
If you were asking about buying the same capacity cell, then OEM or aftermarket alike, you need to first determine whether your control or power module can accommodate a different size. Assuming you can change sizes, a larger cell is virtually always a good choice. However, in downsizing, make sure the smaller cell is still sufficiently large to maintain 1.5-2 times sizing of the cell relative to the pool’s volume.

The CircuPool SJ-Series Electrolytic Cell is a removable titanium electrode and built-in power supply cord, which gets placed into a clear plumbing housing. The SJ cell is unique; its design reduces the need for cleaning mineral deposits and is one of the only systems that does not require acid to clean the cell. Mineral deposits can be removed from the cell with included cleaning wand. The SJ clear cell housing mates to threaded connections on the head of the cell, which allows quick access to the titanium plates for service or winter removal (if applicable). The clear cell makes it possible to see the chlorine generation and to more easily inspect the cell.
