I installed the CircuPool Si 45 plus last year after using liquid for 3 or 4 years after my Aquapure 1400 quite after 5 years. The Si 45 plus had a 7 year warranty and has only been in use for a year. I have flushed it out with water and used the acid mixture to remove the build up. I have been checking it daily starting on Fri 5 June and it does not work with out the acid wash. If i need to clean it every day does that mean it is going out? I like when I don't have to add the chlorine all the time. Does anyone have any experience with the CircuPool brand?
