Breakthrough technology brings laboratory-style water testing to the backyard pool, helping owners enjoy cleaner water, fewer chemical headaches and greater peace of mind.
Every pool owner wants the same thing: crystal-clear water that’s safe to swim in and easy to maintain. Yet keeping pool water perfectly balanced isn’t always as simple as adding chlorine and hoping for the best. Hot weather, heavy pool use, rain, leaves, sunscreen and even the time of day can all affect water chemistry. It’s why many pool owners experience cloudy water, strong chlorine smells or irritated eyes, even when their pool equipment appears to be working properly. Waterco believes it has found a smarter way.
Its latest innovation, Opti, represents a major step forward in automated pool water monitoring by measuring what matters most — free chlorine — more directly and accurately than traditional systems.
The result is water that’s more consistent, easier to manage and more comfortable to swim in.
Smarter Than Simply Estimating
Most automated pool systems don’t measure chlorine itself. Instead, they rely on electronic sensors that estimate how well the chlorine is working. While these systems have served the industry well for decades, the readings can be influenced by changes in water chemistry such as pH levels and other dissolved compounds.
Think of it this way. It’s like checking your body temperature by feeling your forehead versus using a thermometer. One gives you a good indication; the other tells you your actual temperature.
The same principle applies to pool water. Traditional electronic sensors provide an indication of chlorine levels, while Opti directly measures free chlorine using an advanced optical process similar to the testing methods used by professional water laboratories. That gives pool owners a clearer picture of what’s happening in the water. Because Opti continuously monitors free chlorine in real time, it helps maintain more consistent water quality throughout the swimming season.
Better Water with Less Guesswork
For pool owners, the biggest advantage isn’t the technology itself — it’s what it delivers. More accurate chlorine monitoring helps keep water chemistry within the ideal operating range, reducing many of the common frustrations associated with owning a pool.
Water stays clearer and more consistent by helping maintain the right chlorine balance. Swimmers are less likely to experience unpleasant chlorine odours or discomfort caused by water that’s out of balance. By avoiding unnecessary chemical dosing, Opti may also help reduce chemical consumption while extending the life of valuable equipment such as chlorinator cells.
For many homeowners, it means spending less time second-guessing water chemistry and more time simply enjoying the pool. Waterco has also designed Opti with convenience in mind. Compact and easy to retrofit into many existing pool systems, Opti requires only a small amount of reagent for each test. A single bottle is designed to last an entire swimming season for most residential pools, while its simple screw-on replacement bottle makes ongoing maintenance straightforward.
A Win for Pool Service Professionals Too
Opti isn’t just good news for homeowners. It also gives pool service technicians more reliable information every time they visit a customer’s property. Rather than spending valuable time diagnosing water quality issues caused by fluctuating chlorine readings, technicians can make faster, more informed decisions about chemical adjustments and system performance.
More accurate monitoring can also reduce unnecessary call-backs by helping identify water quality issues early, before they affect pool performance or swimmer comfort. It’s a technology that helps both pool professionals and pool owners work from the same, more reliable information.
A New Generation of Pool Care
Waterco has spent years developing and refining Opti through extensive engineering and real-world field testing. The goal wasn’t simply to create another pool sensor. It was to rethink how chlorine is measured altogether. By bringing laboratory-style optical testing into a compact, automated pool device, Waterco has made sophisticated water analysis more accessible than ever before.
As pool technology continues to evolve, innovations like Opti demonstrate that smarter monitoring doesn’t just improve equipment — it improves the entire pool ownership experience. Speak to your local pool shop or service technician to learn how Opti can transform the way your swimming pool is monitored, maintained and enjoyed.
