ACE System Replacement

We Know the ACE and Freshwater Systems.

The Scepter is our own proven factory-direct replacement for the Hot Spring ACE cell. Unlike the original, it works sitting outside the filter, not inside it.

Knockoffs exist for both ACE cells and Freshwater cartridges. Buy from the Wizard to get a supported part that is guaranteed.

Freshwater owners, we also make a longer-lasting replacement cartridge.

  • NOTE: CANNOT BE PLACED INSIDE FILTER LIKE ORIGINAL. IT WILL ONLY WORK SITTING OUTSIDE THE FILTER.

What Owners Say

As an Aria Hot Tub owner I've gone through TWO ACE cells in three years. Two. The first with install cost me 2k. The replacement cell cost me 750. And it just burned out. I was raging. I REFUSE to give Hot Springs another dollar for a faultily engineered part. Especially at that price point. Enter the Scepter. Install was quick. Price was amazing. And it's working beautifully. If you're replacing a faulty ACE cell get one of these IMMEDIATELY. Thanks, HOT TUB WIZARD!!

  • Great product. Terrific customer service!

    The Hot Tub Wizard works great. Highly recommend buying it. Also, I needed a little product support and I was totally impressed how they stand by their product.

    Thank you Mr Wizard!!

  • Works perfectly

    We love our salt water jacuzzi. When we installed the unit, it took a few days to start really producing. We cheated and pushed the boost button multiple times to speed up the production. Zero oder and really nice on the skin. Im a daily hot tub user, i normally have to buy lots of bromine. I have not needed any chemicals for over 2 months. It comes from the factory preset to level 3, I have mine set at 6 to keep up with our usage. Also I touch one of the buttons or booster button when I get out so the unit knows the spa is being used, if you dont do that the system will automatically slow the production as to not make to much chlorine. Ill leave another review in a year or so but as for now we are so happy. A+

  • Reliable and Affordable Replacement for ACE® Sanitizing System – The Scepter Salt Cell® Delivers!

    I use a saltwater hot tub because I do a lot of stupid things athletically, and the salt helps to relieve pain. I’ve been using The Hot Tub Wizard - The Scepter Salt Cell® Replacement for my ACE® Sanitizing System for about 9 months, and I couldn’t be happier with its performance!

    Affordable and Great Value:

    First off, the price is fantastic. I was hesitant to buy a replacement cell because of the high cost of some other options, but the Scepter Salt Cell gave me top-quality performance at a much better price point. It’s a significant cost-saving option without compromising on quality.

    Easy to Install:

    Installation was a breeze! I was able to replace my old salt cell in just a few minutes. The step-by-step instructions made it very simple, and I didn’t need any special tools or expertise. As someone who isn’t particularly handy, I really appreciated how easy it was to get everything set up and running smoothly.

    Reliable Performance:

    After 9 months of regular use, this replacement salt cell has performed flawlessly. My hot tub water stays clean and clear, and the ACE sanitizing system continues to work as it should. The salt system is efficient, and I haven’t had to worry about any issues with water quality or maintenance. It's nice to know I can rely on it, even with consistent use.

    Overall, I highly recommend The Hot Tub Wizard - The Scepter Salt Cell® Replacement. It’s a reliable, cost-effective solution that works perfectly with my ACE® Sanitizing System. If you’re looking for a replacement cell that’s both affordable and easy to install, this is the one to go for!
