Phenix City Al. No pool cover ! All I did was go out and take a leaf rake to it from time to it this winter ( if you could call it a winter). I let Mother Nature take her course. She did a very fine job ! I always run my pump 24 7 during all four seasons and I think I may have backwashed twice. Now we are having weather in the 70s so it was time to open . Water temp is 62 F. right now. FC is 4.0 . PH 7.6 / 7.7 TA is 110. I will try and post images sometime soon. Water clear as glass.. Thank You TFP !!
