Varify 7in1 Pool Test Strips 150 Hot Tub Test Strips and Spa Test Strips

The information that is important for everyone’s purposes is the expiration date for this product. There were other brands that I considered purchasing but I chose not to because the recent reviews had shown that people were being shipped an expired product. Not this one!🥰 As you can see by the photo of the box, it has an expiration date of May 25th, 2025. That gives me a year and a half to use these strips which is perfect for my needs. It is also something to consider when choosing the quantity of strips that you will purchase. Will you be able to use all the strips in the time before they expire? A last thing to add about this is that the expiration date is on the box. It is not also on the container which is typical nowadays. So, before you throw away the box, it might be a good idea to write the expiration days on the container itself. Now I will write about my hydronic system needs so this part of my review may or may not be applicable to your needs. I have been having challenges keeping my hydroponic system in balance so that roots will grow on my cuttings. I finally found a person online that said to use spa test strips to gauge the correct amount of Free Chlorine. So, based on good reviews for some tests, not all tests, I chose these Varify ones. Some reviewers that gave this brand 1 or 2 stars said that the readings on cyanuric acid and calcium hardness are not accurate. So, if that is what you are looking for in a water test, then it might be good to look at the most recent reviews because there is a possibility that this was an issue with just one batch. They may have remedied the test to be more accurate now. However, for my purposes, this test kit is working well in ways that I didn’t even realize were something that Needed to be fixed. I had no idea that water hardness was an issue in my water! Also, my acidity is off the charts low! So, I will be using additives to adjust those things. For now, the difference between the before and after is simply adding bleach. The Free Chlorine reading should be between 2ppm and 4ppm in a hydroponic system. I was shocked to look at the reading (see Before photo attached) of the test before I added more bleach (in a hydroponic system you can add chlorine or bleach as a sanitizer to increase the amount of Free Chlorine). I had absolutely no sanitizer in my system as you can see by the clear swatch next to Free Chlorine. No wonder I was having a challenge getting my cuttings to grow roots! I did the test actually 3 times and adjusted after each time. You can see my final test in the After Photo I attached). You can see that the Free Chlorine reading is now a touch high for a hydroponic system but close enough to work. The test was easy to do, easy to read, and I have hope now of being successful with my hydroponic system. What a relief!

very handy. I perfrom water tests for customers and added this to check for Nitrates. I'm not sure how accurate it is, since the hardness on the tester, was less than the chemical test I used, and use everyday. Can't say which is closer to being accurate, but chemical testing seems more accurate in my opinion.

The Varify 7 in 1 Pool and Spa Test Strips are very easy to use and give a quick overview of the water quality. They’re convenient for checking multiple levels at once without needing complicated equipment. The results are fairly clear, though not always as precise as liquid test kits. Overall, a reliable and simple tool for regular pool and spa maintenance.

The test strips seem to work fine, as expected. The package contains additional useful information about the chemistry behind each test. Included, in addition to the strips in the bottle, was a sealed pouch containing 50 additional refill strips and desiccant, to add to the bottle once the original strips were used up or contaminated. A portion of the proceeds are donated to "Water for Good."

I compared these test strips with the results from my pool store which has an automated system that gives a precise readout of everything on these test strips. These strips were much closer to the store accurate measurement system than my prior strips from Instat*** using the same water sample. Matching the colors on the Varify container was closer to what the strips actually showed when testing the pool water compared to my prior brand.

Good test steps. As advertized.

Works fast and is accurate

So when I ordered this product I got strips in the tube and a refill packet. The strips in the tube were accurate with the exception of the Cyanuric Acid. I started adding that on the low end since this was a new pool with new water. It consistently measured at 0 and never changed. I got to the point where I didn't want to add anymore and risk adding too much. The other day I opened up the refill packet and used one of the strips and it measured right where it needed to be at. So the tube strips weren't accurate with regards to the Cyanuric Acid in relation to the refill packet. I would just make sure that you are paying attention to what chemicals in what amount you're adding just in case they aren't accurate like mine were.

Work perfect easy to view strips

★★★★★ These pool testing strips are easy to use and give quick results. They make it simple to check the water levels and keep the pool balanced. The instructions are clear, and I love how convenient they are for regular pool maintenance. Great product and definitely worth it!

Best strips I’ve used and great value either refill package included. Easier to read than several different brands I’ve used over past 7 years owning my hot tub.

As regular user of test trips on my pool I was pleased with these. They work, are well presented , good clear instructions, and half are sealed, so extending their life. They are excellent value for money and I recommend them.

These are easy to use and easy to read. 2 seconds in the pool, wait 30 seconds and read. The indicator is clear to read and quality. The suitability is for all pools and good value for money.
