Hi All. Well quick overview, opened with algae, cleared it up with SLAM> good levels on everything but water is still cloudy. It has been 7 days, I am seeing SLOW SLOW results in clearing the water, I have held shock level for a week, I know the algae is gone but didnt meet all 3 criteria for slam ( meaning clear water). I have had 0 CC fo a week. I also tried DE in my sand filter Didnt work.. All the equipment appears to be working good. My question is..... ( may be a stupid one, Im a newbee) can I turn my valve on the pump to the main drain to try and filter water thru the bottom of the pool instead of thru the skimmer?? Reason I ask is because the top is clear, its the bottom going into the deep end that seems to be stalled out.
