Poolmaster 22212 Smart Test 6-Way Pool and Spa Test Strips - 50ct

Wait two seconds after submerging, and you have an accurate reading. What more could you want? I have used these for years, with multiple hot tubs at different houses. I keep coming back to these because they check everything you need for a hot tub. The most recent batch though are even better. The plastic is a little less flimsy, and the dye for reading the test seems even a little more vivid. Both are welcome improvements, but they didn't really need any. The reason I keep coming back to these (besides the fact that they are 6-way tests) is that when I take my water sample to the local pool store, I already know what to expect because these test strips are so accurate and easy to read. Like I said earlier, the new dye is an improvements as they did used to be slightly tough to read at times, but with the new dye I have absolutely no issues. It does help to think about what hue you are looking for on each extreme before ever reading the test strip. Then, when reading think about what the hue looks more like and voila - accurate reading when comparing between 2 test colors. Why fix it if it ain't broke? I will not be changing what I use as these are perfect for my needs and am glad I came across them in the first place years ago.

I like the convenience of being able to measure all the chemical levels for your spa using just one test strip. These are convenient to use, provide accurate information to allow us to maintain the proper chemical levels in our spa. As long as the price stays the same ... I would recommend these strips and will purchase them again. Update 08/30/20: So far we've purchased these strips three (3) times now with no complaints. The provide consistent results and work great

I've used these strips for years. They're a great way to get a quick read on your pool chemistry, especially for lazy people like me who don't like to spend the time fussing with water test kits. Just stick the strip in the deep end, swirl around a bit, pull it out and immediately compare against the color chart. Couldn't be easier. When this quick test shows a problem, like low pH, I'll usually break out the full water test kit to get a more accurate reading to determine how to treat the problem. But the vast majority of the time these strips confirm that everything is ok. The date stamped on the tube is about one year from when I received them. About 5 years ago I got a good deal on a small case of tubes and have been using them since. I'm down to the last few strips and noticed that the date code on the old tube is 2013 -- four years ago -- but the strips still work just fine. I even compared a five-year-old strip with a brand new one and they show the exact same readings. So take the "best used by" date with a grain of salt.

This is the best tester for my hot tub. Its super easy to use and only takes 2 seconds to test. I find it is more accurate than some other test strips. Choose this one for your hot tub.

These test strips are great. I use them for both our pool and spa. I have not tested them against any other pool test kits as other reviewers have done for accuracy, but I do know that I have a sparkling clean pool and spa using these as a guide for chemical adjustment. I have not found any problems with reading the results if used as directed. Directions are simple...dip, shake once to remove excess water, and read immediately! The strips are approximately 3 1/2" long and the end you hold is 1 1/2" long so they are easy to grasp when reading results. I will definitely purchase again as they are a good price, and I don't have to go searching other stores for them which can be difficult during off season.
