Lamotte ColorQ Pro 7 Review: Pool Chemistry Made Easy

Trouble by swimming pool chemistry and ever inaccurate brands of test strips? Lamotte ColorQ Pro 7 is all you need to get appropriate balance of Cyanuric acid, pH, Chlorine, Alkalinity, Calcium hardness, and Bromine in your pool water whether salty or not. Why Am I saying this?

Honestly, before I discovered Lamotte ColorQ Pro 7 digital pool water test kit way back in 2011, I used to have real big trouble maintaining my home salty swimming pool water.

Not because I didn't understand pool chemistry, but because different brands of test strips I was using were not able to give me accurate values of most chemicals in the pool, especially Cyanuric acid (CYA), AKA stabilizer, and total chlorine (free and combined chlorine).

If you are a pool chemistry nerd like me, sorry to say;) you know that Cyanuric acid has to be maintained between 50-80 ppm for salty pool water, and 30-50 ppm for non-salty pool water...

...With AquaCheck, the favorite brand of pool water test strip used by most pool guys, I could not find the correct amount of Cyanuric acid in my salty pool water, since it could only measure between 0-30 ppm for low, 30-50 ppm which is appropriate for non-salty pool water, and other readings were 100 ppm, 150 ppm, and 200 ppm.

This meant I could not get the correct amount of CYA acid in my salty pool water, and the only option was to guess the amounts of CYA acid and add the reagent blindly, which left me with ever cloudy pool water.

Another big problem of test strips worth mentioning, I found it very difficult to know the exact amount of total chlorine (free and combined chlorine); which becomes a big problem when shocking your swimming pool as you can use excess or less chlorine.

Of course, I knew the source of the problem as I was somehow sure with the levels of Calcium hardness and pH in my pool: As such, I needed equipment that is able to give me the exact amounts of Cyanuric acid and total chlorine, rather than guessing and matching colors with problematic test strips.

I did a substantial amount of research and finally settled on Lamotte ColorQ Pro 7 because its review and features I found on Amazon matched what I needed for my swimming pool. Ever since I tried this easy to use and accurate digital pool water test kit, I have never had any problem with my swimming pool chemistry.

A Photometer for Digital Reading

Lamotte ColorQ Pro 7 features a photometer that gives you digital readings of all test at a glance. Every test including pH, Calcium hardness, Cyanuric acid, Chlorine, Alkalinity, and Bromine are done using specific reagents that come with the whole pack.

To get readings for your test; just fill the vials with pool water, then add the reagents drops and bam, the machine displays out a digital reading for your test.

7 in One Test Kit

Lamotte ColorQ Pro 7 is able to carry a number of tests in less than 5 minutes. It's easy and fun to use and often times I carry tests for fun on a daily basis just to see how chemicals level decrease slowly until its necessary to add more.

With this equipment; you can carry out the following tests:

  • Free Chlorine
  • Total Chlorine
  • Bromine
  • PH
  • Alkalinity
  • Calcium Hardness
  • Cyanuric Acid

More on the positive side, all the tests for the chemicals above are done using liquid reagents except Cyanuric Acid, which uses tablets. The Lamotte ColorQ Pro 6 used tablets which were very time consuming and oftentimes caused a problem with the tests.

For impressive results, ensure that you always maintain pH between 7.2 and 7.4, Chlorine at 3 ppm, Calcium hardness between 200 and 300 ppm, alkalinity between 90 and 100, and Cyanuric acid between 30 and 50 ppm non-salty pool water, or 50-80 for salty pool water.

Lamotte ColorQ Pro 7 Customer Reviews and Scores

The accuracy of this product makes it extremely versatile when it comes to maintaining pool water: A number of pool managers have used the product and have given positive reviews and ratings; and am bold to say that I found well over 140 customer reviews at the time of writing and they had already awarded Lamotte ColorQ Pro 7 test kit 4.3 stars out of possible 5 on average, and 25 answered questions about the product.

The customer reviews about the product on Amazon are positive overall, but there are few 'negative' points raised: Most of the few negative comments touched on the need to refill the reagents after indicated time frame, which is true.

However, I find this very irrelevant since the reagents are replaced after 1-2 years; which is still cost effective and long enough to buy a kit of new reagents to keep your pool water at bay.

Personally, I order new Lamotte ColorQ Pro 7 Liquid test kit reagent refill pack after a period of 1 year. This period is long enough and most of the reagents are already used up and a refill will be necessary.

On the other hand, expired reagents may not give accurate readings, especially for total Chlorine and Calcium hardness. As such, to be on the safer side, I order new reagents for Chlorine and Calcium hardness after every 6-12 months, just in case.


If at all you are serious about maintaining your swimming chemistry, Lamotte ColorQ Pro 7 digital pool water test kit is all that you need. Without the right equipment, it is hard to find the exact reading of some chemicals such as Cyanuric acid and total chlorine unless you are ready to make endless trips to your pool store.

On the other hand, Chlorine is the major chemical and most delicate chemical in the swimming pool; and wrong concentration of other chemicals such pH will apparently affect its function in the pool water. For example, when pH reaches the upper end of the required range of 7.8, chlorine becomes less effective and may affect your pool water.

As such you need to have exact readings of all the chemicals before you add any into the pool water. To be more accurate, I use poolcalculator or Perfect Pool and Spa software to know the exact amount of each chemical to add to my swimming pool by keying in the values I get from my digital pool water test machine. With all these at your rich, you can never go wrong with your pool chemistry.
