Hot Tub Test Strips: 4 Way Swimming Pool Test Strips for Free Chlorine Bromine & Total Alkalinity & Cyanuric Acid & pH Testing - 100 Quick Accurate Results Spa & Pool Water Test Kit

Same price as the 4 and 6 in 1s, but includes salt! Great product for saltwater pools. Seems accurate, but seeing as I get my only readings from this, hard to tell 😅

This product is amazing , it works very well for my pool. It is very easy to use and its so good and worth the value.

I got these strips to test my hot tub water and they seem to work well. I compared the results to a drop kit and digital pH tester and the pH and Bromine results are consistent. I am unable to test anything else, but I trust they are accurate! the expiration date is in 2028 so they have a shelf life of at least 3 years.

Did exactly what I needed.

I didn't look at the description as close as I should have when I ordered these and was very surprised to see there was no water hardness test. While hardness doesn't change much after I set the hot tub up I still need to measure it to protect the equipment. The other tests worked as expected and had identical readings with my other test strips when I compared them. These will work fine for day to day testing but for setup I will need to use different strips. I have a 1 person tub that holds around 150 gallons of water so the chemical balance can change quite a bit after I've soaked two or thee times. That's why I check it every time I use it.

These make going to the pool supply with a bottle of water a once every other week trek instead of an every Saturday morning trek. Very accurate and easy to use test strips. Will continue to purchase these.

It is exactly the product, I was looking for, tried finding it in local stores but couldn’t find it. This is great and definitely worth the price.

Love these. Work great. Good deal.
