Product Parameters: This black magnetic aquarium glass cleaning brush set includes a small brush measuring 5.6 x 3.5 x 4.2 cm, suitable for glass up to 4 mm thick, and a medium brush measuring 11 x 3.2 x 4.2 cm, suitable for glass up to 6 mm thick. The set is intended for glass aquariums only and is not suitable for acrylic or plastic aquariums.

Core Features: The two cleaning pads work through magnetic attraction on the inside and outside of the aquarium glass. The rough pad is designed to remove algae, stubborn stains, and mineral deposits from the inside, while the soft pad removes dust from the outside. Moving the outer pad controls the inner pad during cleaning, and the square design helps reach corners and other difficult areas. A string hole is provided to retrieve the cleaner if it sinks.

Suitable Uses: Suitable for cleaning the glass walls of aquariums with a capacity of up to 150 liters. Before use, ensure the magnetic surfaces are clean and only use the brush on compatible glass surfaces within the specified thickness range.

Product Summary: A two-piece black magnetic aquarium glass cleaning set with small and medium brushes, designed for algae removal, surface cleaning, and convenient cleaning without having to put your hands in the aquarium.
