It can be a challenge to to keep the water in your spa (or hot tub) crystal clear and odor-free. When life gets busy, it can be very easy to forget to add chlorine (or bromine) to your spa, which can lead to problems, especially since the higher temperature of the water makes that chemical balance all the more important. Spa chlorine generators, like the ChlorMaker for example, can greatly reduce spa problems and spa maintenance since they continuously make chlorine every day so that you don't have to add it yourself.

The ChlorMaker makes chlorine on a 3-hour cycle. Every 3 hours, it starts making chlorine, and based on the power level, it will run for a fixed amount of time and then switch to standby mode. At the next 3-hour mark, it will start again. For example, at power level 5, it will be on for 45 minutes, off for 2 hours and 15 minutes (3 hours minus 45 minutes), on for 45 minutes, etc. If you use the spa and let the ChlorMaker know by pressing the boost button, it will be put into boost mode and run for 3 times the normal amount of time. That way, the ChlorMaker can get a jumpstart on replenishing the chlorine that just got used.
