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.
