Prep the pool according to the post directions or your preferred method.
Review that the cover is clean and free from any debris.
Lay the cover over the pool water, ensuring that it overlaps the edges.
Center the cover so that it covers all sides equally.
Smooth out any wrinkles on the surface of the cover. If your cover wrinkles or sags during installation, reposition it and smooth it out.
Weight the cover down appropriately so it stays in place. Use rachet straps to clip on and tighten, attach the cover to anchors, or use water bags on the edge of the cover.
Notes
To keep debris and snow from your pool cover, simply grab a pool brush or leaf blower. Use either of the two to remove any leaves or snow that might have accumulated on it.
