ALEX® Water Testing
BioGuard pioneered the concept of computerized pool water analysis and has continually refined and advanced the process.
Today, ALEX, our state-of-the-art computerized water analysis system, delivers fast and highly accurate results. Simply bring 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 ongoing maintenance. It’s that easy.
What makes BioGuard’s ALEX water testing different?
Accuracy is everything—and that’s where we excel. Our testing process is significantly more precise than using a simple poolside test strip or a do-it-yourself app. ALEX analyzes multiple parameters—not just the basics—and understands how they interact. This eliminates guesswork, saving you time and money by getting it right the first time.
In addition, our local water care experts are professionally trained and certified. They’ll walk you through your results and explain anything you may have questions about. ALEX’s recommendations are tailored to your unique pool care approach and informed by your historical water test data.
Our goal is not only to deliver excellent performance but also to help you build confidence in the products and guidance you receive.
Why should I test my water?
Regular water testing is essential for maintaining a safe and comfortable swimming environment. Pool water chemistry can be complex, with multiple factors influencing its balance.
For instance, if your water is unbalanced or your pH levels are outside the recommended range, it can lead to issues such as equipment damage, skin and eye irritation, and reduced effectiveness of treatment products. Balanced water is the foundation of any effective pool care routine.
How often should I get my water tested?
We recommend testing your water at pool opening and closing. During the swimming season, water should be tested every two weeks—or at the very least, once a month. Frequent use and environmental factors (like rain, heat, and debris) can alter your pool’s water chemistry quickly. Staying on top of testing helps prevent issues that can become costly or time-consuming to fix if left unchecked.
Why did we name our water testing software ALEX?
ALEX stands for Analysis Expert—and that’s exactly what we aim to be. It reflects our commitment to precision, insight, and expert care in every test.
