The Tunze Care Magnet Strong (022.020) consists of an ergonomic handle and special plastic blades made of wear-resistant high performance plastic. The patented slim Care Magnet is significantly more compact than conventional algae magnets with a large cleaning surface; it is unobtrusive and therefore able to remain within the aquarium without disrupting the overall scenery. With the Care Magnet there is a 3 mm gap between the magnet and the glass so it will not scratch the inside of the aquarium (as sand can not be trapped between the magnet and the glass).

• Magnet dimensions: width 86 mm (3.4 in.), length 140 mm (5.5 in.)
• Suitable for glass thickness from 15mm (1/2") to 20mm (3/4")
• Includes replacement plastic blades
