Dear Mary Ann I want to recognize Mr. Doug Mott for his professionalism, product knowledge and over all outstanding support. A couple of months ago I upgraded my aquarium RO/DI system and working with Doug I decided to purchase the Blue Marlin RO system. I spent a lot of time back and forth on the phone with him working out the logistics and my aquarium water needs. He always gave me all the time I needed and he answered my questions. If he did not know the answer he would research it and get back with me. Recently I have been dealing with a booster pump problem that Doug has taken the lead on to get the problem resolved. I do not know Doug personally other than through your company however I wanted to take this moment to thank him . Sincerely Vincent O’C&*^%* Kingsland, GA 31548
