Jasonwell Magnetic Aquarium Fish Tank Cleaner Magnet Scraper for Glass Aquariums Cleaning Tools Scrubber Floating Brush (S)

Easy and fun way to clean the inside of the aquariums from the outside
Strong magnetic forces cause the inside cleaning scrubbing pad to follow the outside part. Just wipe the outside, and the inside is cleaned!
The inside piece floats, so if it becomes separated from the outside piece, it’s easy to retrieve.
Simply move the no-scratch, felt-lined handle and inside your aquarium, the scrubber follows, cleaning as it goes
Important: Made for common glass fish tank, not for acrylic and low iron glass. Please choose the size by the thickness of your fish tank glass. The larger, the stronger the magnet.
