Cold Plunge Water Care Manual

This protocol keeps your cold plunge water clean and safe using a chlorine-based routine. It's designed for commercial and high-volume settings, but anyone who chooses to sanitize with chlorine can follow it. If your plunge uses the built-in chiller with ozone and filtration and you change the water on the standard schedule, you typically won't need chemicals — see Cold Plunge Care & Maintenance for the simpler routine.

Water chemistry varies with your local water quality. If you're on well water, make sure you can reduce calcium levels before filling — untreated hard water can foul or damage the chiller. Use this alongside your regular cold plunge maintenance.

What you'll need

• Dazzle Amaze — oxidizer; destroys contaminants the filter can't remove.
• Mineraluxe Alkalinity Plus — raises pH and alkalinity.
• Mineraluxe Chlorinating Granules — controls bacteria and algae; raises free and total chlorine.
• Mineraluxe Test Strips — test free/total chlorine, bromine, alkalinity, pH and hardness.

After every drain & refill

Two things to remember: let the water circulate at least 15 minutes between adding each chemical (60 minutes for the most accurate testing), and always adjust alkalinity first, then pH.

1. Fill the cold plunge with fresh water.
2. Test alkalinity and pH with the test strips, then adjust using the tables below.
3. Add 1 cap (12 g) of Dazzle Amaze.

Daily routine

Frequency may increase with heavier use.

1. Test the water chemistry with the strips and adjust using the tables below.
2. Wipe the water line with a sponge as it accumulates.
3. Clean any hair and debris off the drain strainers.
