I've had this problem a little while, After I finish backwashing the pool (inground 25,000gal) I set it back on filter and white milky water starts coming out of the hose fittings, Polaris. I'm assuming its DE. Am I suppose to rinse or recirculate before going to filter? I cleaned and checked the grids for rips and everything seems ok. Also the Polaris wont stop floating to the top? Thank you, Rik
