- THE "ONE-SHOT" MUSTARD ALGAE SOLUTION: Mustard algae has a protective slime layer that standard chlorine struggles to penetrate. Yellow Treat 2 acts as a powerful accelerator, breaking down that defense layer and utilizing your chlorine to kill the algae from the inside out
- RESULTS IN 24 HOURS: Stop brushing your arm off and shocking your pool multiple times a week. Simply broadcast Yellow Treat 2 over the algae, shock immediately, run your filter 24/7, and watch the toughest yellow and mustard algae vanish in as little as 24 hours
- 100% NON-STAINING & METAL-FREE: Unlike copper-based algaecides that carry a high risk of leaving permanent blue or green stains on your expensive pool surfaces, Yellow Treat 2 contains zero metals and zero ingredients that stain pools. It is safe for all plaster, vinyl, and fiberglass finishes
- LEAVES A CHLORINE READING: Specifically formulated to eradicate tough algae while still leaving a residual chlorine reading. It works synergistically with your liquid chlorine or shock, giving you the best of both worlds: chlorine for sanitation and a targeted chemical strike for algae destruction
- HIGHLY CONCENTRATED DOSAGE: A little goes a long way. Just add 5 ounces per 10,000 gallons of pool water. This 2 lb bottle provides multiple treatments to handle stubborn blooms and get your pool back to crystal clear
- COMPATIBLE WITH ALL POOL TYPES: Works effectively in both saltwater and chlorine pools, as well as above ground and inground pool systems, providing versatile treatment options for various pool configurations
- DIRECT KILL TECHNOLOGY: Eliminates live algae directly regardless of phosphate levels, providing a targeted approach that addresses the root cause of mustard and yellow algae infestations in your swimming pool
