Monarch Water and Spa Care

Monarch® Water Care System

Our Monarch® CD Ozone System mixes concentrated ozone bubbles into the water to neutralize contaminants. When used in conjunction with the @ease SmartChlor® Cartridge, you’ll get our most effective water care system. As an option for virtually chlorine-free water care, combine the CD Ozone System with Monarch Silver Cartridges and MPS non-chlorine oxidizers instead of the @ease cartridge. The CD Ozone System is standard on Utopia® models, and optional on Paradise® and Vacanza® models.

MPS Non-Chlorine Oxidizer

MPS is a non-chlorine oxidizer used with the Monarch CD ozone system and Monarch Silver Cartridge to help maintain sparkling clean water in your Caldera® hot tub.

Monarch Silver Cartridge

The use of silver ions inhibits the growth of bacteria and reduces daily spa water care for naturally fresh water. This solution for hot tub chemicals saves time and maintains water quality.

Monarch MPS Plus®

Monarch MPS Plus is a non-chlorine oxidizer with aromatherapy. It helps keep spa water crystal clear, and enhances your hot tub experience with pleasing scents, all in one convenient product.

MPS Test Strips

Use these test strips to monitor your spa’s MPS, pH, and alkalinity levels when using the MPS chlorine-free oxidizer.
