4-in-1 bromine-based testing

This simple 4-parameter test covers the core factors that help you monitor bromine-based sanitization and water balance:

• Bromine levels to gauge sanitizing strength
• pH to support comfort and equipment compatibility
• Total Alkalinity to stabilize pH changes
• Total Hardness to protect surfaces and equipment

Using these readings, you get a practical view of how your spa water is performing, not just a single metric. The results can inform adjustments that keep the water feeling balanced and inviting.
