    Inexpensive test strips for our hot tub. We were having troubles with the ones we purchased from our local pool store. Weren’t getting accurate reads so I decided to go back to what we had to begin with and purchased these. They are accurate and never have given us a false read. Super easy to use.

    After 20+yrs with spas I have determined Lamotte strips are the most accurate with a vibrant color display for all chemicals. The Lamotte 4 is for Chlorine based chems while the LaMotte 5 does both Bromine and Chlorine. Others I had were junk and these last for years.

    The ph reading is a little higher than the actual level, but if you are aware of this you can take this into consideration. I just keep it within the range and it works for me. I would buy again.

    LaMotte brand strip testers are the BEST on the market. reasonably accurate enough to just do spot checks.
    I have tried 4 other brands. This one doesnt bleed to side squares, nor does it produce colours that are hard to compare against. I also find the reference colour chart on the label doesnt fade like other brands (which is extremely important in a colour comparison based test).

    These are the best test strips I have ever used.
    I have used other brand and the colors don’t even match the charts on the bottle. I tested the insta test with my pool test tube water kit and the strips were almost the same results. They might be a little pricey but well worth the money.

    5.0 out of 5 stars Great test strips. Much better than the cheap brands.
    Reviewed in the United Kingdom on July 22, 2017
    Verified Purchase
    These are great test strips. They are more expensive, but worth the extra. These are far superior to some of the cheap brands which I had found to be very unreliable (completely wrong!). I had previously brought some cheap test strips on eBay, and ended up using a lot of chemicals unnecessarily, trying to correct a problem which didn't exist. LaMotte are a proper company who specialise in water test equipment, so I trust these and have found them to be very reliable so far.

    The moral of the story is don't try to save a few pounds by using cheap test strips, as it could cost you a lot more in wasted chemicals, and time spent trying to put things right again. Just buy some good quality test strips (like these), and get it right first time, so you can enjoy your pool!
