The fastest and cheapest and easiest way, if shock is not enough
Fill the pool to the top
Brush with an algae brush, not a regular brush, everything off the sides and bottom. The water will be a beautiful disgusting Solid green
Use the flock and circulate WITHOUT filtering for about 6-8 hours then turn off completely
Let sit for atleast 12 hours.
The algae will drop to the bottom. It looks really cool.
Vacuum SLOWLY to waste. You will have to add water periodically.
Run nothing through the filter.
