Brilliance for Spas 5 Way Test Strips. Each strips tests for total bromine, free available chlorine, total alkalinity, pH and calcium hardness. Fast, easy and accurate results in 15 seconds. Directions: Step One: Remove a Brilliance Test Strip from the bottle. Dip the strip into your spa or hot tub water for one second and remove. Important. Do not 'swish' the strip back and forth, as this will affect the accuracy of the test. Step Two: Hold the strip level, pad side up for 15 seconds. Do not shake excess water from the test strip. Step Three: Compare the color of the pads on the strip to the color chart on the bottle and record your levels.
