AGU030SM Mag-Float Glass Aquarium Cleaner, Small

I use this small magnet to clean the top & sides of my 6g Fluval Edge aquarium. CONSTRUCTION: this set consists of two magnets encased in plastic. The "outside" magnet has a felt surface to avoid scratching your aquarium. The "inside" magnet cleaning material is the "hook" half of a hook+loop (aka velcro) fastener. USE: the Fluval Edge aquarium has a built-on glass roof, and access is through a 5x7" porthole on the top. The inside magnet skips a little on my aquarium glass but cleans green filament algae off my glass easily. PROS: the FLOATING feature is awesome, makes it easy to retrieve the magnet without reaching into the water. CLEANS AROUND CORNERS - The magnet is strong enough that the "inside" magnet just jumps from one wall to the other when you go around corners. very cool and functional. CONS: as with all magnets I've used, the scraped off algae ends up floating away into the tank and getting hung up on my plants. par for the course... BULKY inside magnet housing. A lower-profile magnet would be better for me. The Mag Float is hard to maneuver around my driftwood and plants because it sticks out into the aquarium. OVERALL: cleans well, easy to use on my hard-to-clean and cramped 6gal aquarium.

I purchased this product for my 14gal saltwater nano tank. As a beginner to the world of fish-parenting, I was looking for a relatively cheap product that was reliable, and a great value for the quality. Thankfully, that is exactly what I got with the Mag-Float Glass Aquarium Cleaner in Grey. Not only is it the perfect size for my small tank, it FLOATS! While this may seem obvious, this quality is really what sets it apart. Forget digging around and getting your arm wet when you (inevitably) pull the pieces apart while trying to clean the corners of your tank. With Mag-Float, you'll only ever have to get the tips of your fingers wet, if that! The magnets are strong, so I rarely even have to dip my hands in the tank. Plus, as an added bonus, I never have to worry about Mag-Float falling down the side of the tank. Overall, I couldn't be happier with my Mag-Float Glass Aquarium Cleaner in Grey.

This is by far the easiest, fastests, and least messy way of cleaning most of the algae from my tank walls. It's actually surprisingly easy to use - the magnetics are strong enough to let you quickly move it around corners when needed, and since it floats it's easy to "reaquire" when you do lose the link. It doesn't take a lot of effort to "scrub" this gadget up and down on the glass, and it removes the majority of the algae it passes over. It can be a bit challenging to get around certain objects (e.g. filters, decorations that are close to the wall), but that's to be expected. This is one of those 95% things - it'll get rid of *most* of the algae - the stuff you can reach - for minimal effort.

This Mag-Float accomplishes the job, but not efficiently. However, one cannot fault the product too much as it is simply the nature of the design. It's just too small of a magnet to create enough pressure on the glass. You'll get the algae off the glass, but you'll have to make 10-20 passes (unless you scrape everyday) over the same spot depending on how stubborn it is. Again, this is because the abrasive side, inside the tank, just doesn't have enough pressure behind it. I also own the "Large" model, which works PERFECTLY. Same exact design, only it's size allows it to apply much more pressure to the glass, hence, allowing you to remove algae in 1-2 passes. The reason I did not give this product a low rating is because if you have a small tank (such as my 4 gallon nano), you have no choice but to use the "Small" model. And even though it does not work as well as the larger models, it is still a MUCH, MUCH better alternative to using a sponge or paper-towel, which don't work well to begin with and also require you to submerge your hand in the tank. This can get very messy and time consuming with nano tanks because you would then have to drain some water lest having it overflow when you submerge your hand. Mag-Float put out the best product they could given the limitations a small tank provides. My recommendation is to buy the biggest scraper your tank can fit. If you have anything over 15-20 gallons, spend the extra money and get the "Large" model. The money you will save by buying this one most definitely is not worth the amount of time and effort you will put in getting your glass clean. On the other hand, if you have a very small tank and have no choice but to purchase the "Small," do it, because it's still the very best tool for the job, regardless of it's shortcomings.

I totally love this! Perfect for my 10 gal tank but could be used in a bigger one too. My tank is new so I didn't have any hard stuck on alge to test it on but it's doing a great job of keeping the glass clean. The best part? The strong magnets allow you to move from the side to the front of the tank without having to reach in and grab it. I just jet close to the edge, pull the outside piece off, and move to the next side and the floating piece comes right to it! And I between cleanings i leave it attached in a back corner out of the way but easily accessed. My only problem is where some of my plants are close to the sides and their isn't enough room for it. I may rearrange my tank a bit to fix this.

First aquarium in 10+ years and there’s so many new products that make maintaining a tank so much easier. This is one of them. It’s so easy to slide this around on the sides to clean. I would 100% recommend.

I've had this product for over a year now and loved the concept of a magnet that floats. All to often I lost the magnetic pull and had to resort to some other method to fish (pun intended) the other half out of the tank. It is important that you get the Mag Float that is made for your type of tank (glass or acrylic). It makes a big difference. The cleaning surface of the mag float is like the hard side of velcro and does a decent job of cleaning. It does have some issues with cleaning the really stubborn green algae though. The biggest issue I have with its cleaning ability is that it is that it doesn't utilize the edges well. This is due to the internals of the cleaning end having only 2 magnet points. This allows for good scrubbing in the middle of the cleaner but not toward the edges. An improvement could be made by having a magnet that covers more surface area or 4 magnets (one on each corner). I understand that the more magnets (weight) you have, the less buoyancy you will get. But I think finding that balance will be worth it in the end. Other reviewers have brought up the scratch issue which is a real concern for glass aquariums with sand. When cleaning close to the sand, the magnet (not just the velcro type cleaner) will pick up sand and or metallic grains and scratch the glass easily if you are not very careful. I have easily scratched the glass a few times before I realized what was happening. Pros: The cleaner floats when you pull the outside magnet away from the glass Affordable Cons: Cleaning edges are difficult Using sand in your tank may lead to scratches if not careful

If you are looking for an easier way to keep algae off the glass of your fish tank, then the mag-float is the only way to go. I have used razor blades (which work the best, but only at the correct angle), the Top Fin magnetic glass scrubber, and the Aqueon magnetic glass scrubber. Mag Float is the best for daily use and keeps the algae from building up so repeated scrubbing or using a razor blade isn't necessary. If the magnet becomes separated from the scrubber, the scrubber floats rather than sinks into the sand where it could collect particles that would scratch the glass. Please note, that it doesn't get every part of the glass; corners will still need a razor blade. But it quickly removes algae from the large viewing surface of the fish tank so you can see into the tank and enjoy your fish more often.
