The Yellow Stuff™ Algaecide is a powerful, fast-acting treatment formulated to eliminate mustard algae and prevent future outbreaks in all types of swimming pools. Whether you're treating a breakout or maintaining crystal-clear water, The Yellow Stuff delivers reliable results without foaming or damaging your pool surface.

Compatible with all major pool sanitizing systems—including chlorine, bromine, salt, and ozone—this versatile formula is safe for use on plaster, vinyl, fiberglass, and all other pool finishes. It targets stubborn yellow/mustard algae, which often resists standard chlorine treatments, and works quickly to restore clear, algae-free water.

Common Questions & Instructions

Should I add this while the pump is off?

No, targeted chemicals require thorough circulation. Keep your pump running for at least 12-24 hours after application.

Can I swim immediately after dosing?

We generally recommend waiting at least 2-4 hours after adding specialty chemicals, or until the entire volume of pool water has turned over once.
