Spa Frog Mineral Cartridge

Use this Spa Frog Mineral Cartridge with the Spa Frog Bromine Cartridge in either the in-line Spa System or the Floating Spa System. When the Mineral Cartridge is used as directed, you can reduce bromine levels up to 50% to 80% while maintaining odor free, crystal clear water easily and effectively.
Cartridges are easily adjusted to meet the sanitizing needs of any size spa. Replace the mineral cartridge every 4 months when you drain and refill your spa.

SPA FROG® In-Line System

The SPA FROG® In-Line System, with its patented design, is built right into the spa using the same replaceable mineral and bromine cartridges as the SPA FROG® Floating System. Simply open the cap, pull up the holder and snap in the cartridges. Marquis Spas, Caldera Spas & Emerald Spas are just a few brands that use the SPA FROG® In-Line System.
