The Si-30 replacement cell is compatible with all CircuPool’s Si series control modules except the Si-60. The Si-30 salt cell is the factory original replacement cell model designed to easily drop in place and allow you to replace your old Si-30 cell in minutes. This cell is made to meet or exceed original factory specs and has 100% guaranteed compatibility.

Replacing the Si-30 cell will allow your salt chlorine generator to begin chlorinating again if your old Si-30 salt cell has been depleted. The Si-30 cell sanitizes your swimming pool in an eco-friendly and cost-efficient way, and also helps provide a luxurious swimming experience without the eye irritation and dry skin.

Note: NOT COMPATIBLE with Hayward AquaRite, Swimpure Plus, Mineral Springs, or other related systems.

Sizing:

When replacing your Si-30 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 Si-30 is manufacturer rated for a maximum capacity of 30,000 gallons.

Compatibility:

This replacement salt cell for the Si-30 is 100% compatible with original systems (no software/firmware issues). The Si-30 cell has the same length, threading, and cable connection for direct replacement.

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

How can I tell if my cell needs to be replaced?

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.

Do I have to buy the same cell that came with it?

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.

Replacement cell

Bought as a replacement. Working great and I was pleased with the price. The last one lasted 5 to 6 years. Can't complain.

The Best

Thrilled with my salt pool. Way way cheaper. Maintenance is non-existent and I never lose my crystal clear blue pool now. The staff at Discount Salt Pool that have helped with my Circupool system have been wonderful. Glad to help and quickly resolved any hiccups I've had during installation and chlorine production.

Third Cell Loved Them All

This is our third salt water cell. We love our salt water pool and love the customer service at Discount Salt Pools. We call them when we have a question and they are always very helpful. We consider them the salt water pool experts. Replacing the cells when they wear out is a snap and they last quite a while if you clean them regularly.

Ask A Question

Q: I have an SI Circupool system and need a replacement cell. I thought it was a SI25, but I don't see that option. Is it ok to get the SI30?

Asked by: Beverly Kapp - 4/6/2018

A: Yes, absolutely. Older Si25 models will use Si30 cells, which will be a plug-and-play replacement.

Q: Will this replace the SI-plus?

Asked by: Blake - 5/22/2019

A: Yes, that would be the correct replacement. I'd recommend calling tech support when you have a minute just so they can help you see if your controller's cell type needs to get changed.

Q: Can I replace my existing salt cell from Pentair with this brand salt cell? If so, will it work with my existing computer from Pentair?

Asked by: Lisa - 2/1/2019

A: Unfortunately only Pentair’s cells will work with what you have. The reason is that only Pentair builds in the electronics and controls to that cell, which is also why Pentair cells cost a little more.

If you're looking to save money, you might want to take a look at the SJ-Series systems. They have an adapter kit that makes it a drop-in replacement so its easy to upgrade. Plus it has easier maintenance and the replacement cells are much cheaper down the road.

Here's the link for the adapter. You would want to choose the right size SJ model for your pool after that. https://www.discountsaltpool.com/CircuPool-SJ--HaywardPentair-Cell-Adapter-Kit-_p_184.html
