Keeps our hot tub balanced

One dip and I know exactly where the chlorine, pH and alkalinity are. Way faster than the old drop kit.

Great for the pool season

150 strips is plenty for the whole summer. Colors are easy to match and the results are consistent.

Simple and accurate

Cyanuric acid and bromine on the same strip is really handy. No more guessing with my spa.

Does the job well

Quick and clear. Would like a slightly bigger color chart but readings are reliable.
