Add Yellow Treat®
Add one bag or one capful (5 oz.) of Yellow Treat® per 10,000 gallons of water in the areas with the most mustard algae
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.
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 “super-chlorination” specific dosing.
Let the filter clean up the dead mustard algae, and backwash the filter when the pressure gets high. Refer to the filter manual for back-washing recommendations.
