Hi new to forum. I am living usually in Mt. Pleasant SC and other time in Islamorada Fl. I built my dream house with a gunnite pool and couldnt be happier. When its hot, the hardest decision is whether to walk the dock and go boating, or just be lazy and stay in the pool. Have a question on a chlorinator and not sure if this is the spot to post. Anyhow about how many hours are left when a "limited life" blinking green lite goes on with a Pentair IC20. I tried a 50% mix of muriatic and water to no avail. This was the first time I tried to clean it in 4 seasons of use. Should I just get another one and where would you suggest? Thanks. Ken
