The cleaning pad is made from a special double-sided material that will not scratch acrylic. The pads smooth surface will easily remove algae deposits. The rougher surface of the pads should only be used to remove stubborn marks.

To clean the inside of the aquarium apply light pressure to the pad and work downward from the top of the aquarium. This should prevent grit from the ceramic media being picked up by the pad, which could cause scratching.
