How to Use Lamotte ColorQ Pro Digital Pool Water Test Kit

Lamotte ColorQ Pro 11 Digital Pool Water Test Kit

Are you troubled with swimming pool chemistry? And did you know that the chemicals in your pool are the major culprits causing a cloudy pool water and pool algae of different types? A trouble-free swimming pool begins with a proper balancing of pool chemicals: I thought you should know.

Precisely, if you are having a problem keeping your swimming pool clear, chances are high that you are using a wrong test kit that gives inaccurate readings of pool chemicals.

Without accurate readings of chemicals in your pool, you will never be at peace with your pool, season in season out. Moreover, I hope you will agree with me that the easier the pool chemicals testing process is, the more accurate the test results will be.

Most test kits out there are time consuming and depending on your concentration, these test kits may only give accurate values for chemicals such as chlorine, PH and sometimes a few other pool chemicals such as Cyanuric acid, Alkalinity, and Calcium Hardness, which are all equally important for your swimming pool and should be read very accurately.

Honestly, before I discovered LaMotte ColorQ Pro 7 digital pool water test kit way back in 2011, which has been upgraded to ColorQ Pro 11 to measure metals like Copper and Iron, I used to have real big trouble maintaining my swimming pool. The pool was foggy or call it cloudy most parts of the summer due to the poor balancing of pool chemicals.

Not because I didn't understand pool chemistry, but because the brands of pool water test kits I was using were time-consuming, full of matching colors, and not able to give me accurate values of most chemicals in my pool, especially Cyanuric acid (CYA), AKA stabilizer, and the total chlorine (free and combined chlorine).

If you are a pool chemistry nerd, you know that Cyanuric acid has to be maintained between 50-80 ppm for a saltwater pool, and 30-50 ppm for a non-saltwater pool...

...With AquaCheck test kit, I could only read the levels of Chlorine, PH, Total Alkalinity, and Cyanuric Acid. To make it even worse, I had a problem finding the correct amount of Cyanuric Acid (CYA) in my saltwater pool since values were not numbered in a gradual scale - maybe some changes have been made on it that I don't know about, haven't used it for some time now.

The fact that the numbering for CYA was not gradual meant that I could not get the exact amount of CYA in my saltwater pool, which should range between 50 and 80 ppm, and the only option was to guess the amounts of CYA and add it hoping for mercy, but it was always me and ever cloudy pool water.

Another big problem of these test strips worth mentioning, I found it very difficult to know the exact amount of total chlorine (free and combined chlorine) with a single test; which becomes a big problem when shocking your swimming pool.

Of course, I knew the source of the problem of ever cloudy pool water was CYA, and the only solution was to find an equipment that could give me the exact amounts of Cyanuric acid and total chlorine as fast as possible without any difficulties.

I did a substantial amount of research and finally settled on Lamotte ColorQ Pro 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.

I have also used Taylor Technologies Inc Test Kit; it is easy to work with since it eliminates matching colors, however, I give it a 4-star rating since I cannot measure the value of free chlorine directly, not as fast as LaMotte's test kit, and does not have the measurement for bromine for bromine pools or spas.

Precisely, As far as I am concerned, Lamotte ColorQ Pro has it all; efficiency, simplicity, and most accurate 11 pool chemical tests within few minutes - everything you may need for a clear pool 247 throughout seasons.

Why LaMotte ColorQ Pro 11 Digital Pool Water Test Kit

A Photometer for Digital Reading

Lamotte ColorQ Pro 11 features a photometer that gives you digital readings of all the tests at a glance. Every test including pH, Calcium Hardness, Cyanuric Acid, Chlorine, Alkalinity, Iron, Copper, Biguanide, Biguanide Shock, 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 baam, the machine displays out a digital reading for your test.

11 in One Test Kit

Lamotte ColorQ Pro 11 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
  • Iron
  • Copper
  • Biguanide
  • Biguanide Shock

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 11: Review

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 Lamotte ColorQ Pro 11 test kit has a 5 star rating out of possible 5 on average.

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 11 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 pool chemistry, Lamotte ColorQ Pro 11 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.

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 functioning 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 turn your pool water cloudy or even worse green when pool algae find their way in due to poor pool sanitation.

As such you need to have exact readings of all the chemicals before you add any into the pool. To be more accurate, I use any pool-calculator like 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 kit. With all these at your rich, you can never go wrong with your pool chemistry.
