I moved to a house with an oval above ground pool that was closed for 2 years. The water was black and tried to clean it for 3 weeks but not luck so I emptied it and cleaned it but when I started putting the water back the liner came off of the sides so I emptied again and put sand under the liner and put a inch of water during the hot time but the liner is coming off again.
I don't know what to do . Should I get a new liner ? Or is it another way to fix it ?
