So I do believe I have a small leak in one of my waterfalls after finding water on the underside of the liner opposite side of the pond where the skimmer waterfall is attached. I've turned that one off and let the bottom drain keep going through the night. So last night about 9 I turned off the auto filler and took a shot of the water level. Then I took one this morning at 6:30. Temps are in the upper 70s It looks like its down about a 1/4 of an inch. Is this normal? I do have a lot of rocks on my waterfall. (the bottom drain is the waterfall on the right) I'm waiting for some waterfall foam to come in so I can shore up the liner on the skimmer waterfall after putting on a sealant but just checking to make sure the bottom drain isn't a problem as well.
