SPA FROG MINERAL CARTRIDGE

The Spa Frog 20015 Mineral Cartridge (also known as the FROG Serene Mineral Cartridge) uses silver and other minerals to naturally purify spa water. It's designed to work with either the floating or in-line Spa Frog system, in combination with a bromine or chlorine cartridge, to reduce the need for harsh chemicals. 

Product features:

• Mineral technology: It uses a blend of silver chloride and other ingredients that naturally kill bacteria and help maintain a neutral pH. This reduces the need for traditional sanitizers, like chlorine or bromine, by up to 50%.
• Softer water: By using fewer harsh chemicals, the mineral cartridge helps to make the spa water feel softer and clearer, which is gentler on skin, hair, and swimsuits.
• Hands-free design: The pre-filled cartridge eliminates the need for daily chemical dosing, making hot tub maintenance simpler. You simply snap the cartridge into the designated holder in either a floating or in-line system.
• Long-lasting: The mineral cartridge is designed to last for up to four months, or whenever you drain and refill your hot tub. Even if you still hear minerals rattling inside, they are no longer effective after four months. 

Compatibility:

The 20015 mineral cartridge is designed for use with the FROG Serene (formerly Spa Frog) Floating System or In-Line System for hot tubs up to 600 gallons. Specific models compatible with the in-line system include:
