I have had the EXACT experience as TSA TSA G stated in the review on 9/17/2016. I received the same email and I suspect you will see more negative reviews.
I have had the system since June of 2013. I have spoken to both Rob and RJ in the past numerous times and got the same run around as others. For the past 3 summers I have had a green pool. It is obvious the systems can not control Algae (Green, Yellow, Black) during the summer months when the water temperatures are at their highest. The typical routine is to sell you a new cartridge for $232.79 and its your fault the pool is green.
