Your pool color looks normal to me, it just looks cloudy. Often it takes a long time for sand filters to clear up cloudy water after an algae outbreak.
Did you do the overnight FC loss test correctly? Instructions are in Pool School. If yes, and you didn't lose more than 1ppm, your algae is dead and you need to let the filter do it's job.
Keep filtering 24/7 until it clears, you can also try a little DE in the sand to help improve filtration. Instructions are in Pool School.
