ITS Europe Pool & Spa 3 in1 Test Strips for Free Chlorine, Bromine, pH, Total Alkalinity, 50 test strips

Bought these to supplement existing testing strips. Exact same strips as provided by the spa retailer where we purchased our hot tub. Good value for money.Makes testing a breeze for pH, sanitiser, and alkalinity. Just dip for 5 seconds, wait for 15 seconds and compare colours on strip with colours on back of bottle. Modify chemicals as required, first pH, then test again in 30 mins. Next alkalinity. Lastly sanitiser. Don't just test and add all chemicals at the same time. At least that's the advice that I've read.

5 seconds dip, 1 shake, and compare colours with chart on bottle. Easy enough to use - I alternate between brands of these test kits. Undecided as to which brand is the most accurate, thus the accuracy score of 4, as the different brands don't always compare exactly.

Waste of money.I'm fed up of not finding a reliable test strip from Amazon.These test strips do not give any chlorine reading what so ever..I know there is chlorine in my hot tub I've just shocked it.Clearwater strips showing too much chlorine these test strips showing none..Don't waste your time and miney

Brilliant far cheaper than the best way ones for layzspa and pretty much identical

Good product. Much better that the Bestway ones IMHO

Exactly as described

Good
