How do you remove green algae from an above ground pool if you are not able to vacuum?

i would use algaecide and vaccum and it would coem back after a day or 2 on the surface, i tried brushed and getting it into the mix of the water and algaecide it -samething what i found to work so far is vaccum your floor, back wash the filter and then brush the walls and floor, the water will get cloudy, then add alagecide, then 20 min later add 5 lbs of shock. the water will bubble this is the killing process, run filter 24 hrs and reasses situation. I backwashed again, and checked levels . obviously chloring is still plenty, but i revaccumed, adde dmore algaecide, and ran the filter over night surprisingly the chloring level on the 3rd day was in 40% so the algae ate it. 2 more lbs of shock, and 8 hrs of filter and i can say im in need of a ultra brte, water clarify only i need to pump 8 hrs a day at least 5 times a week, and add algaecide every 5-7 days and ill be ok
