I have a question about my hayward 1hp pump and filter. we just replaced the sand and switched over to swg. since then the return jet has alot of power and it is white cloudy or milky color coming out the jet and when you turn the pump off it bubbles and the skimmer basket turns upside down in the skimmer. any suggestions on what is causing this. the water color is a cloudy blue and not clearing up. HELP
