If you’re like me, your life is busy. Simplify your life, get a WaterGuru. I service my own pool and usually that job falls to the bottom of the list. When the kids call to use the pool, I wonder if the pool water is spot on (since I haven’t stayed on top,of it). I wonder if algae is growing, is my ph right or have my test chemicals gone bad. With WaterGuru all that worrying and wonder – Gone. As I lay on my couch I pull up the app and review the most recent test or initiate a new one.

Absolutely loving my Water Guru.

It was very simple to setup and connect with the WiFi, the direction were clear and easy to follow. I work long hours at night and there are times when I don’t see my pool for weeks. The Water Guru allows me to monitor my pool and know if chemicals need to be added or my chlorinator needs adjusting. I’m looking forward to not coming home to a GREEN pool again.

I started my pool with a very hi ph and no chlorine. Installed the unit after viewing a video. I suggested a picture board included in the shipping box.
It works! I checked my manual test and the unit matched it perfectly!!
