Pawfly Aquarium Magnetic Brush Fish Tank Glass Cleaner 2 Inch Mini Stain Scrubber Pads for 3/5 Inch Thick Fish Tank up to 20 Gallons Aquarium Cleaning Tool with Rope (Not for Acrylic & Plastic Tanks)

• For Glass Tanks Only: Mini size: 2.3" L x 1.3" W x 1.7" H. Perfect size for fish tanks up to 20 gallons. Work great to clean glass with thickness less than 3/5 inches. Not Fit for Acrylic or Plastic Tanks! Strong Magnetism: The fish tank glass cleaner carries strong magnetic force which makes the 2 magnet pads stick tightly to the glass without falling off. Make sure the magnet is clean before scrubbing. Double-sided Cleaning: The coarse pad can effectively scrub hard stains or mineral deposits inside the glass. And the soft pad is used to wipe dust outside. Thoroughly clean the tank to keep it crystal clear. Easy to Use: Just move the soft pad outside, and the coarse pad will follow it to clean the inside. With square structure, the aquarium magnetic brush can clean small corners or hard-to-reach places with ease. Practical Retrieving Rope: Come with a rope to drag the scrubber. Simply pass it through the hole on one pad and fix the rope outside. A cinch to retrieve the magnetic brush if it sinks to the bottom.
