I am sorry about your negative experience with the WaterGuru but on the bright side (for me anyway) you just saved me a lot of time, money, and headache. We just installed a new pool and it's been a long time since we've had one so I don't remember much so I consider myself a newbie. My time is in short supply these days so I am looking for ways to minimize the chores and maximize enjoying the pool. Plus my eyes are no longer what they were and matching up colors is proving more difficult than in the past. I've been looking at the WaterGuru Sense, Sutro SmartMonitor, and Phin. I can't say that I'm sold on them. I was hoping that by now there would be "an app for that" that works i.e. analyses the water then tells me what and how much of each chemical to add and why. Any suggestions? I am thinking about the
LaMotte 2056 ColorQ Pro 7 Digital Pool Water Test Kit but then I need a good chart to tell me what, why, and how much to add. I'll scour around here for a chart. Is there a better testing unit I should consider in the same price range?
