7 in 1 Pool and Spa Test Strips，Hot Tub Test Strips，ph test strips for PH, Total Chlorine, Free Chlorine, Total Alkalinity, Cyanuric Acid, Total Hardness, Bromine（100 Pcs）

Good product but found them a little bit over the top in terms of what you need when you're testing water for suitable quality to use

Does what it says on the tinEasy to use no hassle

I was concerned that I appeared to have no chlorine in my spa even though I had just added some so I made a very strong solution and the strips still failed to work. Complete waste of money.

Great value, great for use on spa easy to read, will buy again

These strips do not work.On 2 other manufacturer's strips the level of chlorine was reading 3ppm and pH 7.4 but nothing at all on these strips. I am concerned that if these were the only strips someone had they could be raising the chlorine to dangerous levels as these strips don't seem to read anything in the water.

I thought I would give these a try based on the low price in comparison to the clearwater and aquachek ones.Unfortunately I was unable to get anything close to the colours on the chart, Ive used numerous brands before with both a hot tub and pool and these gave the poorest result.
