There are very few things in life that are true “game changers” in an industry. #Sutro is one of them. I was nervous getting a pool, but this incredibly advanced and accurate device takes nearly ALL the guesswork and fuss out of owning a pool. From 3x daily readings of your pool’s Free Chlorine, pH, and Alkalinity (sent right to your phone), plus on-demand temp readings, and exact dosage amounts of the chemicals that you use based on your pool’s specifications, you cannot go wrong with this device. It’s thoughtfully designed and incredibly well built. It is the ONLY pool maintenance system that uses Lamotte Reagents, the most accurate way to measure pool chemistry. #NotAnAd #MemorialSutro @mysutro (at Allen Park, Michigan) https://www.instagram.com/p/CPjAt3hBPhX/?utm_medium=tumblr
