Even when life gets busy the pool is tested.
“I am retired, and didn't think I would need/want something like the WaterGuru. But it sounded interesting so I bought one. I'm so glad I did.Those times when pool maintenance gets away from you, or because your away from home for a few days, you can always check on the fly to make sure everything is where it should be when it comes to your chemicals.”
David A, Arizona

Far better than test strips.
“The first thing most people are going to say is that it’s expensive, and I can buy lots of test strips for that price.Both items are valid, but the big difference is you are getting accurate readings and tracking of data.A test strip only gives you an approximation of where your levels are at.It’s a guessing game as to what the accurate reading is based on color.Guess wrong, and you are either out of balance or wasting chemicals.WaterGuru saves me money.”

The perfect tool for the job.
“I have been using WaterGuru for over a year now and it's the perfect tool. The historical graphs and the daily status on PH and Free Chlorine have given a much better analysis to keep the pool in a balanced state. Now, I can understand how rain, heat, and sunlight affect the pool chemical level without spending a lot of time performing the measurements.”
