AquaChek Yellow 4 in 1 Hot Tub Test Strips

There are dozens of types of hot tub test strips available and many are very poor quality but these are very good. The water stays separated better instead of flowing between each test pad. And these are the only tests you need for a hot tub 99% of the time: Chlorine, pH, Alkalinity, and Stabilizer. Chlorine kills the germs, pH makes chlorine work and prevents skin irritation, Alkalinity makes the pH easier to correct, and Stabilizer tells you when its time to change the water. Simple! 

Includes 50 strips per bottle.
