Tunze has reinvented the magnet glass cleaner with the Care Magnet.

• Special plastic blades made of wear-resistant high-performance plastic
• Plastic Blade life - several months to approx. one year
• Compact design with large cleaning surface area
• Inner magnet is more than 3mm away from the aquarium and prevents jamming of aquarium sand
• Angle of blades against glass, remove more algae than a flat blade

• Dimensions - 1.57" x 3.19" (40mm x 81mm)
• Glass Thickness - 1/8" to 1/4" (3mm to 6mm)
• Non-removable plastic blade

not recommend using these cleaners for acrylic as there is a chance they may cause scuff marks.
