150Pcs 3-Way Hot Tub, Spa and Pool Test Strips

If you live in a warm area, be sure to store these indoors. I have a nice waterproof box by my hot tub and tried storing these in it with some of the chemicals. It was fine over the winter, but now that it's above 85 outside, the strips are discoloring. The Alkalinity and PH are WAY off....PH reading is a much lighter orange 7.0 vs actual 7.4, and the Alkalinity reading is much darker....almost 100 points higher! I confirm strange readings with my liquid test kit, so no harm done.Just want to warn others before they start dumping in adjustments and making things worse. The color changes were gradual at first until the temps hit the 90's. The Bromine scale still works pretty well, so at least they aren't totally useless.

Easy to read test strips that show solid readings when in or out of range. When compared to lab water tests, there is some slight variation in ppm to color readings on the test strip, but not enough so that when numbers are compared to lab/water tests that they are out of acceptable ranges. We have had consistently great water test readings across the board since using these test strips.We have even been personally commended by our local water testing facility for the cleanest water tested this season. With these strips, we are able to confidently do our own chemical balancing without as many visits to the pool store (aka the chemical salesmen!!). We could not have achieved this without reliable home test strips. Not to mention, we have saved so much in chemicals from accurate strip readings rather than relying on the readings and recommendations from the pool store alone.I highly recommend these strips to anyone who is looking to balance their own pools at a fraction of the cost of strips (and chemicals!) from the store.

I’ve had these EASYTEST 7-Way Pool Test Strips for a little over a week now, and they’ve been working really well. I’ve used them multiple times to test our small above-ground pool, which is about 10 feet wide, 33 inches deep, and holds around 1,500 gallons. The strips feel durable, are very easy to use, and the instructions are simple to follow. The results show up in about 15 seconds, which makes checking the water quick and convenient. Based on the results, I’ve been using baking soda to raise the total alkalinity, which helps stabilize the pH and prevents it from changing too quickly. I’ve also used alkalinity increaser along with pH increaser or pH decreaser as needed to keep the water in the proper range. With 150 strips in the package, these should last me quite a while even with regular testing. Overall, they’ve been a great value and have helped me keep the pool clean, balanced, and ready for my family to enjoy. I would definitely recommend them.

They work pretty good, consistent for the most part. I also use a electronic test meter and the old school drops. I only do this just to try and get a more accurate average across all the readings. PH and chlorine are all very close with drop and electronic tests. Takes some time to get used to the colors much easier to tell what color it should be when using the three test method as described. But after a few times of doing that you get pretty good at being able to rely on the strip. 4 stars only cause sometimes they are little off compared to my other testers.

I really like these pool test strips! One of my favorite things is that they test for more water parameters than many of the other strips I’ve used, so I get a better overall picture of my pool’s water quality. They’re easy to use, the color chart is simple to read, and having 150 strips is a great value. They’ve made it much easier to keep my pool balanced and looking its best.

If you have a pool or hot tub, you need chemical strips. These are all the i fo you need without anything you don't. Quick and easy to read.

Very simple to use. Used the Taylor test kit for years before finally deciding to try the EASYTEST 7-Way Pool Test Strips. The test strips are a quick way to get the condition of your pool water without the hassle of using the mixing method required for the Taylor test kit. I am still comparing results between the two, but so far both testing methods are returning the same results.

I just wanted a quick chlorine test and decided to get these PoolSpa 7-way EasyTest strips to see how they work with respect to my Taylor test kit. These strips do quite well on the chlorine test. They don’t do so well on the PH test. They read about .5 lower than the Taylor test kit. The strips don’t work well at all on the CYA test. The strips show 0 for cya. The Taylor kit shows 40-50.I have had my pool for 25 years. I know how the water reacts in pretty much any (im)balance scenario. The Taylor kit has the cya right while the test strips do not. My water is holding the chlorine level quite well. If cya was 0 I would be adding a lot of chlorine maybe to the tune of a gallon per day at least. These strips are inaccurate with respect to cya levels.That doesn’t mean they are useless. They are inexpensive and once my water is balanced I only do a chlorine test daily and a PH test weekly. I think I can just add .5 to the PH result so the strips work for most all testing I do after pool open and proper water balancing.I’m going to do both the strip and the Taylor a couple more times to verify the PH test results and if the .5 low PH on the strip is consistent, I will then just add .5 to the PH results and use the strips for the rest of the season.On the positive side, the strips are easier and quicker to use than the Taylor kit. I might buy them again or I might try another test strip in the future. There are a lot of strips in the bottle so I probably won’t use them all for at least the rest of the season. If anyone finds strips that are accurate wrt chlorine, PH and cya, I hope it’s possible to respond to this review or “ask me a question” and tell me the strips that work.One more note - my local pool store is selling a case (4 gallons) of liquid chlorine for about $7.50 per gallon before tax. The chlorine is 12.5%. If anyone knows of a source that has cheaper chlorine, even if it’s just 10% let me know.

Quick to use, excellent strip for overall pool health check, chlorine level and pH balance is my primary concerns the others are good to know for fine tuning and comfortable pool use. Durability is good and suitable for pools. Colours on the strip seem accurate enough to make a judgement call on the adjustments that needs attention.

Most 7 in 1 tests that I've come across have been roughly $55 for a 100 pack.. assuming these are affective, it's an amazing find! Very simple and striaght forward to use too.

The strips didn't work, kept reading ph wrong. I bought distilled water to double check - consistently read it at a ph of 6. I tried another sample if purified water - did the same again.

I've used twice the recommended amount of chlorine for the size of my pool, but these test strips stubbornly give me a reading of 0ppm.I'll use another brand.

Son fáciles de usar, 1 segundo en el agua y listo y permiten comprobar los parámetros con los colores del bote. La escala de colores se entiende bien. Por cantidad y comodidad, mis 5!
