It’s an itsy-bitsy, lean, high-energy, window-cleaning apparatus that slips safely between polyps and viewing windows. NanoMag has the umph needed for cleaning windows up to 1/2” thick, and it glides across the curved surfaces of fish bowls, wiping off algal films with ease. It’s so much fun to use you just might have to take turns. Patented design by Julian Sprung.
