Hello, we have an Intex krystal clear saltwater pump. We had been having a few problems with the low flow sensor going off with error code 90 and gave up trying to get it to work 5 days ago. After another go today we have managed to get it going with no beeping or error messages. It has now been going for several hours and is running fine. The problem is that the pool looked almost picture perfect (it was a tiny bit cloudy) before running the pump and now the pool is a greeny yellowy brown colour that is getting darker the longer the pump runs for. Does anyone know what is causing this please, and how can we fix it? Thanks
