Happy Premium 4-way Pool & Spa Test Strips (50 Pack)

Happy Hot Tubs Premium 4-way Test Strips offer a clear, concise and easy-to-read method of measuring the parameters in your swimming pool or hot tub. Each pot comes sealed at the top with 50 strips inside and a clear comparison chart on the back.

These test strips are great for salt system users (such as Hot Spring ACE or Hot Spring Freshwater Salt) as they contain the hardness reading.

Test Parameter	Ideal Range
Free Chlorine	1-3ppm for Pools 3-5ppm for Hot Tubs
Alkalinity	80-120ppm
PH	7.2 to 7.8
Total Hardness	25-75ppm for salt systems. 75-250ppm for non-salt systems.
