A solar cover then. They make it hard to keep a pool clean because the skimmers don't work to remove surface debris before it gets waterlogged and sinks.

Probably two options:

Leave the cover off or get a cleaner that will work under the cover. However, green is from algae and is the result of insufficient chlorine for the CYA level in the water.
