Using your skimmer net, remove as much large floating debris and “algae patties” from the pool as possible.
Set your system to “vacuum to waste” and using your pool vacuum remove as much large debris and sludge from the bottom of the pool as possible.
Add Swamp Treat™
Add one (1) bottle of Swamp Treat™ per 20,000 gallons of pool water.
Brush the walls of the pool. One good brush over the wall should be fine.
Add approximately 2 pounds/gallons of chlorine pool shock per 10,000 gallons – cascading it around the pool.
Run the Filter
Set your system back to filter, and turn the pump on. Allow to filter for 24 hours. Continue to filter and backwash as necessary until pool clears up.
