You can’t just jump the gun on buying a floating pool chlorine dispenser to chlorinate your pool. What you should consider is- whether the bromine dispenser functions properly or not. The following criteria we mentioned will help you to pick the best chlorine dispenser. 

Adjustable Control Ring

To chlorinate your chlorine pool or spa, you must ensure your spa or hot tub gets the right amount of chlorine. Before purchasing a floating chlorine dispenser, make sure it comes with an adjustable control ring. It helps to deliver the proper amount of chlorine in your swimming pool to balance the water.

Energy-efficient or Not

A chlorine dispenser can’t merely propel or float around your pool by itself. It needs energy or power to swim and dispense chlorine around your pool. Most chlorinators use electricity as their energy source, which may spike up the electricity bills (though most models we mentioned on the list are energy-efficient). Regarding this, you can go for a chlorine dispenser that is solar-powered to chlorinate your hot tub, spa, or pool in an energy-efficient way. 


Your chlorine dispenser will remain in your pool, spa, or hot tub. So, you should pick the chlorinator that doesn’t get corroded. In simple words, get a floating chlorine dispenser that uses non-corrosive components as its built-in materials.
