I just got a 21 round above ground pool installed 9 days ago and it has been filled with water for 7. I have a temporary electric hookup and when the electrician dug the trench 5 days ago I believe dirt blew into the pool. I still have not used pool as electric should be finished today. I vacuumed the pool slowly 5 days in a row now and the dirt comes back 5 minutes after I clean the filter and turn it back on. The filter cartridge is dirty before I clean it. I tried disconnecting the return hose and run it for a minute then put it back on and dirt comes back. I even tried panty hose around skimmer basket which has stopped some dirt but not enough. I know it has to do with filter system because I left the pump off for 2 hours one day after vacuuming and pool was perfect. Any ideas to get rid of this annoying dirt? I shocked and conditioned the pool the day after filled and have put chlorine tablet in daily. Pump is running 8-12 hours a day do chemicals were tested and good. Water is crystal clear so I am sure it is dirt and not algae plus pool is brand new. Has anyone tried filter socks or automatic vacuums like Wanda the whale or diver Dan?
