Pool water testing made easy! – Clorox Pool Review

I've been testing water for years for fresh and saltwater aquariums and I wish there was an app that worked this well for those. Some reviewers complain that it "used" to work but now only works for pools. I've only used it since the last update so I don't know what it used to say, but it now says it's not for spas "at this time." All I know is it works great on a 4,000 gallon above ground. Takes the guesswork out of dosing.
