The new ChlorMaker DO by ControlOMatic is a drape-over spa saltwater system specifically designed as an affordable way to retrofit any spa in the marketplace. Operating on a three-hour cycle, it efficiently manages the continuous sanitation needs of spas holding up to 1,250 gallons. Additional features include adjustable output, automatic self-cleaning, salt level indicator and usage boost mode, which dramatically reduces spa maintenance typically associated with traditional sanitation methods. Simply place the easy-to-use, push-button control panel on the spa skirting, add 1.5 pounds of salt per 100 gallons of spa water, install the cell and plug it in.
