Upgrade to Next Larger Size for $10
- It's Wise to Oversize!
ControlOMatic MegaChlor replacement electrode cells are specifically designed to retrofit your existing salt system on hot tub, spas, or small aboveground pools up to 12000 gallons. This replacement salt cell installs in just minutes: simply remove the 4 screws to open the ChlorMaker control box, loosen the 2 terminal post screws, and remove the old electrode.
The MegaChlor Cell simply drapes over the side of the hot tub into the water when you desire active spa sanitation, the spa doesn't even have to be on or running! The clear cell lets you see it working and allows for easy inspection.
The optional inline cell can also be installed out-of-sight directly into the existing spa plumbing when appropriate (see manufacturer recommendations)
