There are four parts to the all POOL FROG Mineral Systems - the Cycler, Mineral Reservoir and the pre-filled chlorine Bac Pac.
The patented Control Dial on the front of the Cycler lets you manage the amount of water flowing through the system. Water is circulated upward into the Mineral Reservoir and chlorine Bac Pac simultaneously. The erosion design of this system continuously dispenses chlorine at a precise low level (only 0.5 is needed). Once you've determined the correct setting for your pool just set it, then forget it for weeks at a time!
