You bought an Intex Pool last year and your water flow is way down, water is not clear and the Intex salt chlorine generator won't work because the water flow is below the working threshold. You tried everything including replacing a less than year old pump and filter system. Maybe it's time to look at replacing the Intex pump and filter with a better quality but affordable pump and filter set. For Intex pools less than 15,000 gallons, we are recommending Game Sand Pro 50 Filter System. It is more durable that the Intex filter-pump system and very reasonably priced.
