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.

ACE and Freshwater are registered trademarks of Watkins Manufacturing Corp., makers of Hot Spring and Caldera Spas. The Hot Tub Wizard & Pool Spa Efficiency, LLC are not affiliated or endorsed by Watkins MFG. in any way.

Real Owner Feedback

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!!
