Water Testing Made Easy

We make time for our routine car maintenance and we go to the doctor to get our annual wellness exams, and pool water is no different. Maintaining your pool isn’t a difficult process, just like going to the doctor for a check-up isn’t overly straining. 

Putting in the leg-work to maintain your pool is going to not only give you peace of mind but will keep your pool safe and functioning at peak efficiency.

To test your pool water, you’ll need a test kit. Apersonal favorite is the LaMotte ColorQ Pro 9 Plus. It has a digital reader, and the process only takes a few minutes to run each test.  

Test Kits 

How do you know your swimming pool needs to be tested? You can easily tell when the pool is dirty because it becomes murky or green.Even if your water is crystal clear, your outdoor paradise could have excess levels of certain minerals. You have no idea what’s lurking just beneath the surface, and that’s why running tests is vital. The main levels your test kit will be examining are: alkaline, chlorine, cyanuric acid, calcium hardness, and pH. 

Each kit will designate where your water should fall on the respective spectrum, and usually correcting an unbalanced mineral is an easy fix. For example, if your chlorine levels are too high, simply remove your pool cover. The sun’s rays will burn off the excesschlorine, and you can add new water that will balance the remaining levels.  

Once youhave completed a test, werecommended to wait 2-4 hours before you resume swimming. If you want to be extra careful, wait a full filter cycle, which can last up to 8 hours. A second test might be necessary as an added safety precaution. Note– if you’re going to run a second test, wait at least 24 hours after completing the first.  


With the LaMotte ColorQ Pro 9 Plus, testing your pool should not take you longer than a few minutes. The biggest thing that you should consider before blocking out your Saturday morning is if you’ve done the prep-work. That includes gathering about a cup of sample pool water, reading through your respective kit’s instructions, and understanding how to run the test.  

The LaMotte ColorQ Pro 9 Plus has a digital reader, but other kits require the old school method of dipping test strips without any computerized assistance. Take the time to ensure you understand how your kit works before you dive right into it. Pro tip: many kits will provide a color-coded guide for mineral levels in the water. However, this is not universal across kits.  

To keep your pool water clean and healthy, test the water at 2 ends or sides of the pool at least twice a week. To best keep organized, we recommend recording your results each time you test.
