– Pool and Spa Test Strips 50 Counts: 3-Way Hot Tub Test Kit Testing for Free Chlorine/Bromine, Total Alkalinity, and pH. Easy and Accurate Spa Test Strips for Hot Tub

I’m very happy indeed to give these a 5 star rating! They test the water safety levels by measuring that the ph balance, chlorine content, absence of algae etc so that I know beyond guessing that my hot tub is safe to relax in. They’re really easy to use, giving the test result in seconds, and I can trust they’re functioning correctly each time because it’s a basic chemical reaction readout, not a measured digital reading. Very happy with these indeed, and they’re certainly the go-to test strip for protecting our family and friends.

easy to use

As stated

These are the best strips we have had for the use in our hot tub. These results are easy to read after you have dipped the water and the colours match well to the colours on the bottle. work well in any water quality.

Done the job

Verified these against two different brands and found them to be completely wrong on alkalinity, Wlwhich is now sky high as they indicated the need for ph+, and almost zero chlorine. Hottest week of the year coming next week and the pool is unusable 🤬 Avoid!

No point buying expensive, they all stop working 6 months after working. These are in packs of foil, so might last bit longer. Good product at a good price.

Not as good as the ones I usually buy the colours are different and take longer to change colour.
