Onzen Electrode | 3-Plate Replacement Salt Cell

Keep your Onzen system performing at its best with this genuine Arctic Spas 3-Plate Replacement Salt Cell. The electrode threads in and out like a light bulb — a tool-free swap that takes seconds — and an annual replacement keeps your salt water system producing chlorine at full strength all year.

When you'll need a new cell: the classic signs are chlorine output that keeps dropping even though the salt level tests fine, a system that runs longer and longer cycles to hold sanitizer, or visible scale and wear on the electrode plates. Cells are consumables — a year of daily electrolysis is real work.

Will this fit my spa? Yes, on Arctic Spas with the Onzen 3-plate salt water system. Spas with the newer SpaBoy system take the 5-Plate SpaBoy Electrode instead. Not sure which you have? Bring the old cell to one of our three Ontario showrooms.

Quick tips: inspect the electrode for scale every few months and soak it in Salt Cell Cleaner when deposits build — a clean cell lasts noticeably longer. How to change your cell: https://www.youtube.com/watch?v=FKVK7mjiE-E
