Yellow Treat
5 ounces per 10,000 gallons
From Florida to California and everthing in between; Mustard Algae is the most common form of swimming pool algae. Odds are if you’ve owned a swimming pool, you’ve ran into this yellowish sandy looking algae growing in the shady areas of your pool. Here we give you step by step directions on how to get rid of mustard algae.
Steps
minute(s)
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.
Leave items like pool toys, equipment, and floaters in the pool during treatment. Leaving them out and not treating them increases the risk of reinfecting the pool with mustard algae when they get thrown back in.
Mustard Algae (often referred to as Yellow Algae) is a resilient, chlorine-resistant form of algae that typically appears as a yellowish-brown, dust-like powder on the floor or walls of your pool. Unlike green algae, which floats and clouds the water, mustard algae tends to cling to surfaces—particularly in shady areas of the pool—and is easily brushed away, often resembling sand or pollen. Because this strain has a protective outer layer that allows it to survive in high-chlorine environments, standard shocking is rarely enough to eliminate it; it requires a specialized algicide designed to penetrate its defenses.
