I’ve have had a Chlorine Genie for almost 2 years. I can only say the product is the best and the support is incredible. The system is so easy to use and saves me $$$$ hundreds in pool chemicals. I keep very accurate records and can say, I have spent less then $ 40 on acid and conditioner in the last 20 months. My pool is sparkling and refreshing all the time. I highly recommend the Genie to anyone interested in simple pool maintenance. All you need is to test weekly, adjust PH settings on Genie as needed. I would also recommend a robot vacuum and an occasional brushing of the pool walls but the Genie saves you time and money. I also recommend you join a few pool forums on the web and follow the BBB pool methods. Bottom line is you can say good buy to buying any chemicals from the pool store other than a gallon of Acid and conditioner once a year.
