I was recently contacted by a realtor asking for help getting pool winterized. Pool has not been used or maintained for several years. I used a skimming net to drag muck sticks debris even fiberglass insulation that found it's way to bottom of pool. I drained pool down to 1 for on shallow end which left 5 for on deep end. I have scrubbed algae from sides and bottom as best as I can tell. Pool water is too cloudy to see if there is still algae on bottom, however I have scrubbed and swept pool daily for 10 days straight. Before turning on pump I replaced and in filter and scrubbed Hayward 300# filter before replacing sand. I am at a loss what to do now. I listened to guy at pool store who said I needed phosphate remover to get rid of cloudiness. After reading threads here I now know that was not good idea. I wish I found this site before starting pool. Water has a greenish hue still keeping my visibility impossible. What would you recommend to proceed with. I am concerned that pipesplumbing could be infected with algae. I tried Slam method my chlorine levels are still high. Where do I go from here.
