This review is waaay overdue (I just cleaned out my desk and finally found the service tech's card after many months!), but I just wanted to say that Zach Horton of Aqua Science is a very thorough, knowledgeable, competent, clean, and trust worthy tech. And as a bonus, he is about the nicest young man you'd ever want working in your home.
Good job Aqua Science, for providing such great (and pleasant) service!
