Step-by-Step

Step
1

Add Swamp Treat™

Add one (1) bottle of Swamp Treat™ per 20,000 gallons of pool water. 

Step
2

Brush

Brush the surface of the pool, concentrating on areas with the most mustard algae. One good push of the brush over an area should do the trick.

Step
3

Shock

Shock the pool with your choice of chlorine – using about 2 pounds/gallons of chlorine per 10,000 gallons of pool water. Refer to the directions on your chlorine for “superchlorination” specific dosing.

Step
4

Filter

Let the filter clean up the dead white water mold, and backwash the filter when the pressure gets high. Refer to the filter manual for back-washing recommendations.

What You’ll Need

  • Swamp Treat™ Rescue Algicide
  • Brush Attachment
  • Pool Shock of your choice

Extra Tips

  • Check the filter pressure every few hours and backwash as necessary. Your filter may clog quickly depending on how much white mold you have.
  • Keep your filter running continuously to help get rid of the algae.
  • Backwash your filter when the filter pressure rises above 10 psi than normal.
  • Don’t pour shock directly on colored surfaces. This can discolor your surface.
