Step
1
Add Swamp Treat™
Add one (1) bottle of Swamp Treat™ per 20,000 gallons of pool water.
Step
2
Brush
Brush the walls of the pool. You’ll need to get as much of the black algae off the surface as possible, so some scrubbing might be needed.
Step
3
Shock
Add approximately 2 pounds/gallons of shock per 10,000 gallons – cascading it around the pool.
Step
4
Filter
Set your system back to filter, and turn the pump on. Allow to filter for 24 hours
