Fairly new to pool ownership but things have been going well I think over the past 6 months. We have an In-Ground pool (small at around 12K Gallons). Its got a SWG (Hayward Salt and Swim 3C) my issue is that even on the lowest setting It generates too much chlorine since we don't have much if any swimmer load since its still too cool. Is this a common issue? My other numbers seems to all be right where they should be but FC if left on the min setting climbs to around 6 or 7 at which point I turn it off and allow the levels to drop back down. It's kind of taking the whole automated chlorine away!
