Frog Ease 3 Pack Cartridge Sundance
With SmartChlor™ Technology, there is always a reserve of chlorine waiting to be used. When needed the reserve automatically converts to free chlorine which maintains a consistently low level.
Dichlor tabs tend to have yo-yo chlorination while SmartChlor™ Technology keeps the free chlorine in the 0.5 to 1.0 range at all times.
The Spa Frog @Ease Sundance Spa Sanitizing System is built-in hot tub water care that puts you at ease.
