Ok, the front skimmer door has a waterline imprinted on the skimmer. So I installed it where I thought it would be best. It will be easy to raise it up some by adding dirt or some gravel under it. It’s my understanding that the water line on the skimmer determines the water line in the pond. Once I both out some of the dirt in front of the skimmer, it will be easier to see where I want the water level. Also being that the skimmer sits back from the inner edge wall of the pond. What is the best way to attach the liner to it properly? Won’t the ledge around the pond make the liner not attach correctly? I could always Motch the dirt in front of the skimmer in a bowl shape extending about 1’ on each side of the skimmer. That might help with the liner install to the face of the skimmer. I just want to make sure there is no tension on the liner where it is attached to the skimmer. However I want to save a little excess liner near the skimmer for any adjustments down the road.
