Clear Magic Powder will purify your aquarium water right before your eyes! The fish do not need to be removed from the aquarium when Clear Magic Powder is applied to the system. Clear Magic Power forces organics in the aquarium to clump into larger molecules, allowing for easier pick up by your aquarium filter. Clear Magic Powder will also help keep the glass or acrylic walls of your aquarium algae free in between cleaning. Safe for Freshwater and Saltwater Aquariums. 1 packet treats up to 30 gallons of aquarium water. 5 packets per box.
