Free Water Testing


Our stores are temporarily closed. However, you can complete an online form and drop off a water test at the door or any of our 4 locations. You may wait for the results or we can contact you when the results are completed. If balancing chemicals are needed, you may purchase sanitation chemicals over the phone for curbside pick-up.

Thank you for your patience at this time.

Visit Zagers for FREE Pool or Spa Water Testing

Come into any one of our 4 West Michigan locations for a free computerized water test, where our water specialists can determine if any levels need to be adjusted for a clear, algae-free pool or spa. No appointment is necessary.


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

Water testing is important to achieve and maintain a safer swimming environment. 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.

We recommend using a regular water bottle that has never held any products that could alter the test results, such as pop or other acidic liquids. For your convenience, free water bottles are available at all 4 of our locations.

We recommend collecting water at least 18” from the surface so that you aren’t just skimming water off the top of the pool or spa. This ensures a more accurate reading. Also, try to avoid grabbing water near the return jets or skimmer (chlorine levels can be higher if you use sticks/tabs in the skimmer basket).
