Robelle’s 21-pound bag supplies concentrated cyanuric acid designed to dissolve rapidly and bring pools into the recommended 40–100 ppm range. Use a reliable pool test kit to measure current cyanuric acid, follow the included dosing chart, and recirculate water after application for full dissolution.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly does Robelle dissolve and take effect?\u003c\/h3\u003e\n\u003cp\u003eThis powder is formulated to disperse rapidly so stabilizer levels rise soon after application.
