If you forget to add chlorine or bromine for a single day or the chlorine feeder runs out and you don"t refill it that could lead to spa problems. Due to the higher temperature of the water the chemical balance is critical to be continuously maintained to keep it safe. Proper spa maintenance leads to your spa being safe when you want to use it. Even if the water looks good you should measure the chemical balance before use. Spa chlorine generators can greatly reduce spa problems and spa maintenance as they continuously make chlorine (or bromine) every day so you don"t have to. The TechniChlor makes chlorine on a 3 hour cycle. Every 3 hours it starts making chlorine, and based on the power level it will turn off at some point in that 3 hours and remain in standby mode, then at the next 3 hours it will start again.
