How does the Pool FROG 5400 work?

The POOL FROG sanitizing system uses a combination of minerals and a LOW level of chlorine that creates Fresh Mineral Water. It starts with the Cycler that is installed after the pump and filter. Then the Mineral Reservoir is inserted inside with minerals that destroy bacteria all summer long. The Bac Pac^® goes in next and precisely dispenses the small amount of chlorine needed for each pool. Everything is pre-filled for no mess, no guess and no stress. Simply replace the Bac Pac every 1-3 weeks when empty and the Mineral Reservoir every 6 months. Less work leaves your pool for nothing but fun!
