ALEX® Water Testing

BioGuard pioneered the idea of computerized pool water analysis and we have continued to research and refine the process. Today, ALEX, our computerized water analysis system,​ provides accurate results in an instant. All you have to do is bring in a water sample from your pool or spa to your local BioGuard Dealer​ and you’ll receive personalized step-by-step instructions for start-up, closing and maintenance. It’s that easy!

How is BioGuard’s ALEX water testing different?

Here accuracy counts and we have it! Our 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.

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. Our ALEX recommendations will be sound based upon the way you care for your pool and the accumulated knowledge of all your previous water tests.

Our goal is that you will not only be satisfied with the performance results, but that you gain confidence in the products and advice you receive.

Why should I test my water?

Water testing is important to achieve and maintain a safer swimmer environment. Water chemistry can be quite complex with all the different factors.

For example, if your water is out of balance or your pH isn’t in the right range it can cause problems, such as equipment damage and swimmer discomfort. Balanced water also contributes to the effectiveness of other products so it is an important start to your water care regimen.

How often should I get my water tested?

We recommend you get your water tested when you open and close your pool. In season it is recommended to test every two weeks or minimum at least once a month. The amount of use and environmental factors can easily change water conditions and staying on things will prevent issues that may prove troublesome to correct if neglected.

Why did we name our water testing software ALEX?

ALEX stands for analysis expert, which is who we are.
