An Algae Magnet allows you to clean the glass inside your aquarium without getting wet. A strong magnet on the outside holds the inside cleaning pad in position.
Instructions:
Place the abrasive pad on the inside of the aquarium and whilst holding, bring up the smooth pad until the two halves hold together through the glass.
Move around as required to clean inner surface of the glass.
Suitable for aquarium glass up to 6mm thick.
