Nice job...now if only the grand kids pool wasn't round...lol. It doesn't have a solar cover, it's vinyl to keep out debris and help keep algae from growing in it also I imagine. It has small holes in the center then other small holes punch out in different area's. I've never seen one like that and since the pool was donated to us by someone moving out of state it's way better than buying a new one. I am not sure the holes are there for safety reasons or to let rain water run off the cover into the pool or excess water that somehow gets on the cover to drain so it's not logged down with water while getting the cover off....but it doesn't quite work that way and often would have water on top and made it difficult to get the cover off....until this bright light went off in my head and said "hey leave the kids tubes in there and the cover will sit over top of them therefore not touching the water....and it works wonderfully! Sometimes you just got to be thankful for the small things in life....lol.
