Good absorb ability and powerful magnetic attraction. As you move the outer magnet, the inside magnet follows,hence cleans the glass. The inside brush will not sink into the farthest depths of fish tank as it is floating. Super strong magnets for use with varying glass thicknesses. Floats avoiding lost magnets on the bottom of your aquarium. Anti Scratch cleaning pads that are highly efficient in removing algae from glass. Non slip griped handle improving cleaning action. Material:Plastic and high magnet material.

Algae on the inside of the tank can ruin the look of even the nicest aquarium and most beautiful fish. Here's the easy and fun way to clean aquarium glass, with no awkward long-handled tools or dunking your whole arm into the tank. In an elegantly simple design, strong magnets lock the two parts of the cleaner together through your aquarium's glass, so the cleaning brush on the inside follows the handle on the outside. The inside piece has short plastic bristles to safely clean away algae, and the outside handle has an easy-slide felt surface. If the two sections should become separated, it's no problem; the inside piece will float to the surface.

Note:

1.If a piece of aquarium gravel should become lodged between the cleaning brush and the glass, stop wiping immediately to prevent scratching the glass. Just lift the handle away and let the cleaning brush float to the surface.

2.Do not use in Acrylic fish tanks and super white fish tank. Package:
