The HASA Liquid Feeder™ uses a simple technology that is better for the environment.

As an added value for purchasing SutroHASA Liquid Feeder™, you can get one free gallon of Hasa Sani-Clor when you buy 4 at your local pool store in California or Arizona.

Why Sutro?

Sutro saves you time and money. The app sends you quick readings 3x/day so you always know your exact pool chemistry. Never add in chemicals that your water doesn't need.


All you need is a pool or spa and an internet connection for Sutro to work. Our device works great with chlorine, salt water, mineral, and bromine pools and spas.


Today, you will purchase the Sutro Sytem for $499. Once you receive your device, you will be able to choose premium ($39/mo) or basic ($29/mo) service within the Sutro App. This includes the cost of monthly cartridges shipped to your doorstep.

Customer Service

We're on standby. Sutro's success team is available at the click of a button to solve your water problems.

"I ordered one and I can't wait to use it in my pool. This will save me from having to go out every morning checking water balance. Plus, I don't know what I'm doing if the water gets too imbalanced. I'm super excited."


  • Chlorine Pool/Spa

    No matter whether you use pool chlorine tablets or liquid chlorine, ditch the chlorine test strips and let Sutro help you keep your water clean and clear so your pool will always be ready when you are!

  • Saltwater Pool/Spa

    Sutro can help you manage your salt chlorine generator by checking your chlorine levels 3x/day and letting you know real-time if you need to adjust your chlorine generator or if your pH or alkalinity is out of range.

  • Mineral/UV Pool/Spa

    Even with these systems there is still a need to maintain a lower concentration of chlorine or bromine. Sutro can guide you with custom treatment recommendations for pH, alkalinity, and chlorome/bromine so that your pool is always ready when you are!

  • Bromine Pool/Spa

    Sutro can help you keep an eye on your bromine levels so your water stays clean and clear. Ditch the inferior bromine test strips and let Sutro provide you with treatment recommendations so you can rest assured that your pool will be ready when you are!

How It Works

The Sutro Smart Water Monitor makes it easy to maintain a perfectly balanced pool or spa without having to fiddle with water samples, test strips, or messy test kits. Simply drop the monitor into your pool and check your phone for up-to-date readings and advice for balancing its water chemistry when necessary.
