QNCIGER7-Way Pool Test Strips,50 Strips Water Chemical Testing for Hot tub and Spa, Accurate Test Total Hardness,Total Alkalinity, Cyanuric Acid,Total Chlorine,Free Chlorine,Bromine and pH

The strips are all of uniform length and width, with the raised tabs evenly spaced apart, the strips are easy to read and more accurate. The old method of getting pool water, hoping the test chem drips are not to much or too little and mis-judging because of sunlight is tedious. These test strips will make it much easier to test the pool, just dip it in and pull it out. The raised pads of the test strips do make it much easier to observe the color changes in direct sunlight.

I use these for my hot tub and they were accurate. They are easier to read than the strips that use the pink range. I will buy again.

I have an ice bath in which the water is filtered and ozone treated to enable longevity of the water. The clarity of the water is a good general indicator of the water health, however this doesn't tell you the full picture so using test strips is a good idea to get a more in-depth indication of the water health.These strips come in a pack of 50 in a little tub. You dip them in the water for a few seconds and then hold them horizontally for 30 seconds to get the results. The tested elements are water hardness, total alkalinity, cyanuric acid, total chlorine, free chlorine, bromine and pH. The colour strip guide on the side of the tub shows what the ideal readings are so if the strip colours don't match some corrective action may be required. In my case I don't use chlorine or bromine in my water so I'd expect them to show a low reading, but other than that everything seems good. They appear to work very well and the results are as expected. Overall I am happy with them and think they are good value for money.

Easy to use strips for checking quality of water in the swimming pool. We got big pool 1st time and not really sure if doing everything correct, so these strips help us to see if water is clean and safety for children. I am not sure if it very accurate, but I hope. To understand result, you just need to check picture in the box and strip for matching colours. Price is good. Recommend it!

A tub of 50 testing strips for your pool, measures a number of different chemicals and has handy chart / key to read on the outside of the bottle. Works well with the results being accurate.

These strips work well and change colour that is easily viewable. A great clear key on the side of the pot to tell you what the colours mean.

Easy to read, consistent range of colours so it was easy to get your levels right. So often they are wishy washey colour levels but these aren't.Good value as well.
