Start with Clean Water

Make the most of your hot tub water care system with these chemical-free accessories to ensure you start with fresh, clean water.

Clean Screen®

Attach this pre-filter to your garden hose to remove organic contaminants, tannins, copper, iron and other metals from the water as you fill your spa.

Vanishing Act®

This calcium remover reduces buildup for softer-feeling water that's silkier on your skin. It helps protect your spa from the damaging effects of hard water.

Mineral Spa Sanitizer

Add onto your preferred water care system for the best spa water!

A silver purifier cartridge inhibits bacterial growth. Simply insert the cartridge into the filter of your spa and the silver ions are released automatically — there's no chance of under or over-dosing. Simply replace the cartridge every four months. Available for use with all Caldera spas.


An Ozone System mixes concentrated ozone bubbles into the water to neutralize contaminants such as lotions, detergents and organic waste. An ozone system uses fewer chemicals and can be paired with FROG sanitizing systems. Ozone is not intended for use with the FreshWater® Salt System.
