Features

  • WHY YOU NEED ONE - Easy removal of algae from glass/acrylic surfaces. No longer knock over decorations, damage corals and invertebrates. No longer get your hands submerged into the water of the fish tank. Time/money saver on maintenance. Large cleaning surface area makes the job quick and efficient. Stays free of debris. Can be maintained attached to aquarium surface. Strong, high-quality neodymium rare earth magnets. Magnet does not lose strength over time. Easy retrieval of inner magnet.
  • HOW TO USE - Clean outside aquarium surface thoroughly before each use. Remove all debris from Mag-Float prior to each use. Do not use Mag-Float above waterline or on dry surface. Keep Mag-Float away from the gravel line and glass aquarium sealant. The magnet part with logo Mag-Float is placed on the outside aquarium. The Mag-Float can be left attached to aquarium surface, it's constructed from toxic-free ABS desigend for aquarium use.
  • KEEP YOUR HANDS DRY - Clean your aquarium glass while keeping your arms dry! The Mag-Float is the ultimate floating magnetic aquarium cleaner made using powerful rare earth neodymium magnets. By dragging the Mag-Float along the outside of your tank, the inner Mag-Float magnet follows, effortlessly scraping off any algae as it goes.
  • IT FLOATS - If your inner magnet happens to disconnect from the outer magnet-- no worries! The inner magnet will simply float to the top of the aquarium, keeping your hands dry and saving you time in pesky retrievals. Using the float feature, you can easily and efficiently move around tank corners without knocking over decorations or damaging corals and invertebrates.
  • DESIGNED FOR THIS - The Mag-Float cleaning pad remains free of sand and gravel, thus preventing unsightly scratches to your aquarium glass or acrylic. Because it is constructed from toxic-free ABS plastic, you can even leave your Mag-Float attached to your aquarium 24/7, making it a convenient and practical choice. Strong, high-quality neodymium rare earth magnets. Can be used on freshwater and saltwater tanks, special sizes for betta bowls, curved glass and huge aquariums.

  • Fantastic tool for cleaning the glass
Size: 1 Count (Pack of 1)
The media could not be loaded. I have been using a sponge with a handle to clean my fish tank and it was a mess and not efficient. I switched to this handy, magnetic gadget and couldn’t be more pleased. It is so easy to use and maneuver. It’s heavy duty with a strong magnet. It doesn’t scratch the glass and it’s effective to get heavy buildup off the glass. For the money you can’t beat it, it’s a great value. ... show more

  • Works pretty well
Size: 1 Count (Pack of 1)
I got this with the scraper blades because when the seasons changed, my aquarium a different angle of sunlight and I had some growth of spot algae that I couldn't get off with my rubber scraper. Using the mag-float as intended worked fairly well but didn't get off all the spots. What I ended up doing was not using the 2nd piece, the one for outside the aquarium. Instead, I held the half attached to the blade in my hand and scraped the walls manually while wearing gloves. The spot algae came right off when I did that. ... show more

  • Strong magnets and floating = don’t get wet hands
Size: 1 Count (Pack of 1)
I had one of these already for several years but needed the kind that supports the removable razor scraper blades (sold separately) since there was some stubborn algae in one of my tanks. I like that you can leave it in your tank for easy daily cleaning, and if you pull the outer magnet off, the inner one floats so you don’t have to fish it out of your aquarium. Even getting things from the bottom of a ten gallon gets messy, so being able to easily grab it from the surface is much quicker and dryer! ... show more

  • Love it
Size: Medium
I have had 200 gallon tanks for past 30 years and this is the only product I will use. I have tried two others only to find that they started to scratch the glass. These never scratch and the magnet is so strong that my 10 inch parrot fish who like to attack it when I’m using it can’t get it off. These are worth every penny ... show more

  • Wish I had this the whole time
Size: 1 Count (Pack of 1)
Makes cleaning glass fun and wish I had heard about it and purchased sooner! Be careful not to hurt fish or snails as it is an extremely strong magnet when it comes together.

  • Excellent for my curved tank
Size: Medium
This product easily removes algae from my curved glass tank. I've been using one for used but it got so gross I decided to buy another. Run the magnet horizontally if you have curved glass and for sure avoid the last inch on the bottom because it will pick up sand and scratch the glass.
