Water Testing FAQs

Water testing is important to achieve and maintain a safer swimmer environment. Water chemistry can be quite complex with so many different factors, and testing frequently can help avoid problems like swimmer discomfort or equipment damage, saving you money and preserving valuable pool time with your family.

Bring in your water in a clean jar or water bottle, then we will replace that with a free water testing bottle for your future visits.

It is important to have your pool and spa water professionally analyzed beyond just the basics at opening, closing, and every few weeks in between to keep it safe and clean. You should also be using at home test strips a few times a week to maintain balanced water throughout the season.

At a absolute MINIMUM, please bring in your water sample when you open and close your spa or pool. This is how you set the foundation for balanced water.

If you cannot test your water regularly, consider having our water maintenance team perfectly balance your water weekly or bi-weekly.

At-home tests cover the basics, but our professional chemical test in store (Bioguard’s high tech testing system–ALEX. See below) is fast and much more accurate than a simple dip of a test. 

We test for several parameters beyond the basics to understand how they may be influencing each other and consider accumulated knowledge from previous water tests. On top of that, our local water care experts have been trained and certified. They will walk you through the results and are happy to explain anything you might have questions about!

We use BioGuard’s computerized water analysis system, ALEX, which provides our trained experts with accurate results in an instant. All you have to do is bring in a water sample from your pool or spa to any of our stores and you’ll receive personalized step-by-step instructions for start-up, closing and maintenance. It’s that easy!


Our computerized water analysis system    provides accurate results in an instant. 

Here accuracy counts and we have it. Alex is the best water testing system in Canada. 

Our water test is fast and much more accurate than a simple dip of a test strip at poolside or a self-driven analysis using a computer or mobile application. That’s because we test for several parameters beyond the basics to understand how they may be influencing each other in order to avoid trial and error. 

Being right the first time saves you time and money. Your water will cause you less stress and increase fun in your pool and spa when you work with our water experts.
