RockWaterAir 3-Way Plus Test Strips (Free Chlorine, Bromine, pH & Total Alkalinity) Test Strips for Hot Tub and Swimming Pools 50 chemical dip test strips

Think I've had better sticks, not convinced of accuracy and colour comparisons on bottle.. Will use them up but would probably look for others next time.

I tried these after having used the Clearwater strips. They are almost as good as the Clearwater ones.

I bought these as a result of reading the reviews which stated that they are accurate. However, I have compared them with the strips I already use and they DO NOT read the free chlorine levels. The pad stays the same colour with very faint colouring around the outside.

Quick and easy to check water quality in hot tub. It just takes a few seconds

Okay

Work just as well as the last set we had which had half the number of strips in, so much better value

Good

Handy little strips to keep the water just right
