The Right Way to Test

1

Test Alkalinity First

Always start with alkalinity - it's the foundation of balanced water. TubTest guides you through the drop test with a built-in counter.

2

Balance pH

Once alkalinity is stable, test pH. Get exact dosing for pH adjusters calculated for your tub's volume.

3

Check Sanitizer

Finally, ensure proper sanitizer levels. TubTest handles both bromine and chlorine systems with precision.
