For Glass Tanks Only: Measure 1.8" D x 2.3" H. Perfect size for fish tanks up to 30 gallons. Work well to clean glass with thickness less than 4/5 inches. Not Fit for Acrylic or Plastic Tanks!
Strong Magnetism: Strong magnetic force makes the 2 magnet pieces stick tightly to the glass without falling off. Always follow each other to clean both sides with ease.
Double Pads: The coarse pad can effectively clean inside the glass. And the soft pad is used to wipe dust outside. Thoroughly clean the tank to keep it crystal clear.
Non-slip Design: Comfortable grip due to its concave surface. Tightly grasp the brush to move it flexibly. Easily clean small corners or hard-to-reach places without getting wet.
Float If Detached: The 2 pads float on the water surface and won’t sink to the bottom when separated. A cinch to retrieve them without disturbing any of your aquatic lives.
