i have a intex 15x53 pool I purchased the bigger pump and everything was working perfectly. now am starting to notice that the pump isn't pumping out like it used to. it sounds alot louder like its working harder when I turn it on. the water is always cloudy I changed the filter still the same. i checked the lines the gaskets everything seems to be fine. I even started to rinse the filters every time I turn on the pump and still it's the same. any ideas on why it's acting funny.
