The JBL Floaty II magnet is highly effective and will allow you to remove algae and other deposits from your aquarium glass. No need to get your hands wet; simply guide the glass cleaner from the outside. Because it's a well-known fact: cleaning the glass is one of the least favorite tasks for aquarists! Removing deposits like algae or dirt isn't easy and can even become annoying, especially in hard-to-reach places. The JBL Floaty II glass cleaner magnet makes the task easier and helps you enjoy cleaning the glass. It consists of two parts, an outer and an inner part, with strong magnetic force. Simply place the inner part on the water's surface near the glass, then place the other part on the outer glass. The inner part is then attracted to the outer part and is easily guided. Thanks to its strong magnetic force, dirt on the glass is effectively removed without the need to get your hands wet. Its flat shape allows the magnet to clean even corners and hard-to-reach areas. Furthermore, its beveled edges won't damage silicone seals or scratch the glass. The inner element won't fall to the bottom of the aquarium and therefore won't trap any grit that could scratch the glass. The JBL Floaty II magnet thus guarantees gentle and effective cleaning. Once the glass is clean, simply remove the outer element. The inner element will then detach from the glass and float on the surface of the water for easy retrieval. The JBL Floaty II magnet is available in several sizes with different cleaning surfaces. Features of the JBL Floaty II magnet: Floating aquarium glass cleaner magnet keeps hands dry: you guide the magnet from the outer element; no scratches: the inner element won't fall to the bottom of the aquarium and therefore won't have any trapped gravel that could scratch the glass; patented edges: beveled edges to protect silicone seals; easy to use; efficient cleaning; available in several sizes
