Aloha from the big island. I had to pretty much leave my pool for the month of Feb to the elements and now I have a green pool. I shocked it a day ago. Waited a day and went and got some algaecide added that.. four hours later added phosphate remover.. before all this I did run the pump and I brushed the sides and bottom . Running the pump now going out to test the chemicals. It's still cloudy but not as bad. I'm new to the pool ( above ground 3400 gallons)
