Fast, accurate water testing made for bromine systems. AquaChek® Red 4-in-1 Test Strips deliver reliable results in seconds, making them ideal for spas, hot tubs, and bromine-treated pools. With one quick dip, you can monitor the key balance factors that affect water clarity, comfort, and equipment life.

Unlike basic test strips, AquaChek® Red includes a Total Hardness test, which is especially important in warm water where scale can form more quickly. Regular testing helps you stay ahead of problems—protecting heaters, pumps, and surfaces while keeping water comfortable for bathers.

Measures 4 Essential Parameters:

• Total Bromine

• pH

• Total Alkalinity

• Total Hardness

Why Pool & Spa Owners Choose It:

• 4 results in 1 dip for fast, convenient testing

• Dip for 1 second, remove, and read results in seconds

• Designed specifically for bromine-based systems

• Hardness testing helps reduce scale buildup, especially in hot tubs

• Supports balanced water, bather comfort, and equipment protection

PTL Direct Pro Tip:
For spas and hot tubs, test the water before and after heavy use. Warm water accelerates scale formation, so keeping hardness in range helps extend heater and pump life.
