4-Way - Hot Tub, Swimming Pool and Spa Test Strips - Bottle of 70 - Measures Chlorine, Bromine, PH and Total Alkalinity - Made in the USA.

Exactly what the headline says, easy to use, pretty accurate (tested alongside the Clearwater strips for a similar result) and a good price. Plus I like the fact it's a small family business as I like to support small where I can.

Very good quality pool and spa test strips, does everything you would expect, really liked that you can test for either chlorine or bromine along with total alkalinity and pH….Good value pack it contains 70 strips in a pot. Has a very clear instruction insert that makes how to do the testing easy! Would 100% recommend :)!!

Good quality easy to use and understand

These test strips are excellent value as there are a lot more strips in the pack than other brands for a similar price, the strips are easy to use and clear to check against the colour coded key on the storage container.

use it twice a week in the hot tub to keep an eye on chlorine and Ph levels. ideal waterproof pot that lives in the garden box next to the tub. Easy to use and reliable results

Seem ok. Not used yet.

delivered straight away and much easier to read the levels than others on the market.

These test strips certainly seem to give accurate results. My only very slight frustration is that the differentiation in colours for the chlorine levels is so small that it can be difficult to distinguish between low and’OK’.
