Aquascape Rapid Clear Flocculent quickly clears cloudy pond water by clumping suspended debris. This will quickly help to provide clear water conditions and allow particulate to be captured and removed from the pond. Rapid Clear works within 24 hours, providing noticeable results and allowing you to spend more time enjoying your pond. For best results, use in combination with the Rapid Clear Fine Filter Mat (model 80001). Rapid Clear is safe for fish, plants, pets, and wildlife. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
