PoolDoc recommends running the filter 24/7 when trying to clear a pool. Green tinted water with 0 combined chlorine is usually an indication of metals in the water. Do you fill with a well or city water? Have you added any algaecide lately? Is there copper in your "Super Chlo"?

You might want to do a DE test on your filter
