What else can you do if you have a very dirty above-ground 21-foot pool and you've vacuumed it scrubbed the sides and shocked it several times but the water is still cloudy and greenish in color?

First, take a sample of the water to your local pool dealer. It could be that your algaecide isn't a high enough strength. You may have to add it and run you filter for 12 hrs X 3 days. Change your sand in your sand filter.
