How do you vacuum above ground pool?

Buy a vacuum head, not one with wheels, one meant for a vinyl liner. Buy the hose. Attach the hose to the vacuum head and place in the water. Fill the hose with water by placing the other end of the hose in front of the return jet in the pool. Attach the hose to the hole in the skimmer. If the pool is full of leaves and mud, set the pump to waste and blow the water out of the pool. Be sure not to let the water level fall below half of the skimmer. Add more water if necessary. If the debris in the pool is minor, you may leave the setting on the pump on filter but you should backwash and rinse the filter head afterwards. For minor debris, you may also buy an automatic bottom moving vacuum. They really are great!
