Multifunctional 6-in-1 Swimming Pool Test Paper Water Tester Strips For PH, Total Chlorine, Free Chlorine, Total Alkalinity, Cyanuric Acid，Total Hardness (50)

Great item. Really helped see if my pool was safe to use and save emptying the water daily and wasting such volume. Definitely will be buying again

Brilliant product, the multiple indicators are just what I needed, amazing price and quantity per pot, I will 3back

Got these for my hot tub.Although I don't have anything else to compare them to they seem to give good readings every time i use them.Have done two at once before just to make sure the readings were true and they came out the same.I may buy another brand just to see if the readings do match up near enough then I would know if they are correct or not.Happy with what they are doing at the mo.

This order arrived on time and is just as stated, happy with the service.

For the few days of summer that have not rained these worked well

Poor .Not a true reading .Avoid

I did not like these test strips. I could not get an accurate reading. I felt the colours on the strips did not match the colour on the pot.

Rubbish ,just tested spa with these and thought that cant be right,the Cyanuric Acid was off scale. so used my Aqua check and spa was fine. Tested them in plain water from tap and all but chlorine were wrong.acid off scale .dont waste your money .
