Aqueon Aquarium Algae Scraper, Fish Tank Cleaning Magnets for Glass/Acrylic, Medium

Crystal-Clear Glass Made Effortless As someone who takes aquarium maintenance seriously, the Aqueon Aquarium Algae Scraper Cleaning Magnet (Medium) truly exceeded my expectations. The magnetic strength is perfectly balanced — strong enough to power through stubborn algae, yet smooth enough to glide effortlessly across the glass without scratching. What impressed me most is how efficient it is. I can clean large sections of the tank quickly without getting my hands wet, and the inner pad stays aligned without slipping. It makes routine maintenance faster and far less disruptive for the fish. The build quality feels solid and thoughtfully designed for both glass and acrylic setups. It’s simple, effective, and reliable — exactly the kind of well-engineered product I appreciate reviewing and recommending. A must-have tool for any aquarium owner who values clarity and convenience.

Great quality, very strong magnets, this is perfect for my 10 gallon aquarium. It comes with 2 scrubbing pads that snap into place so you can use it for glass or acrylic tanks. The pad for glass has a warning printed on the back to advise it is ONLY for glass, that will help you tell them apart if needed. Otherwise blue scrubber for acrylic and black scrubber for glass. This is very effective at cleaning the inside of the tank. Intuitive design and size. There is a nub on one end to keep the scrubbing above the substrate. You can go slowly around the corner and the scrubber will hop to stick to the next side of the tank. This does not float, but will sink straight down if separated. This is my 2nd one to be able to keep nearby for both the upstairs and downstairs tanks. You can compare the included before and after pictures - on the before pic you can see the clean paths from snail travel on the inside of the glass, on the second we are nice and clear - victory!.

The Aqueon Aquarium Algae Scraper in the small size is a strong, easy‑to‑use magnetic cleaner that makes routine algae removal quick and low‑effort. Its magnet has enough power to stay connected while you scrub, and the weighted inner piece drops straight down instead of floating away if it detaches. The included pads for both glass and acrylic make it versatile and safe for different tank types. It glides smoothly across the walls and handles everyday algae buildup well. Overall, it’s a reliable and affordable tool that keeps small aquariums looking clean with minimal work.

This effortlessly removes algae from the inside of my glass aquarium. It has two different cleaning surfaces, and the bristly surface cuts through stuck on algae so much better than my traditional tank brush on a stick. The felt surface is not nearly as effective as the bristly surface. I accidentally bought the smaller size and thought I'd regret it, but this is a product that takes hardly any time at all to use and it's very efficient at removing the algae growth, so I have yet to see the need to upgrade to the appropriate size for my tank. Overall, this leaves my glass tank sparkling clean and I'm so appreciative of the time it saves me cleaning the aquarium. There's been no damage incurred from use of this product on my glass tank walls. And, bonus points, it's now a chore that my young children can help out with and they enjoy driving the algae cleaner around the tank cleaning algae from the sides. The only complaint I have is that sometimes the magnets don't line up perfectly when I try to maneuver around corners and if they line up wrong, it can make the two sides repel each other, resulting in me having to fish out the half that goes inside the tank and trying to get it aligned correctly again. So I do wish that the magnets were slightly stronger so that it would be easier to go around corners without the halves falling away from each other.

Use this on my big acrylic tanks. Works phenomenal. Cheap, simple, easy. Does a lot better on glass, but still a game changer for acrylics. Just be careful not to pick up and sand or you’ll regret it.

I got the medium size for my 29 gal aquarium which is the perfect size. Comes with 2 scrub pads depending on if you have glass or acrylic. Works really good at cleaning the sides of my fish aquarium, at least the glass scrubber as I dont have an acrylic tank to test. I highly recommend this product as an essential part of keeping your aquarium pristine.

Love this for my 3 gallon! Really gets the algae off with one quick swipe!! The magnet is strong and you can ease past the corners. Highly Recommend!

Worked OK for a little while until the blue pad started coming apart.

Bought the medium version which is ideal for 10mm glass. Cleans the glass well and, so far, it hasn't become detached from the outside magnet. It's quite hard work though! The only problem, which is minor, is that the inside magnet tends to vibrate or oscillate as it travels, unless you move extremely slowly. This sets up small pressure waves through the water, enough to make the heater elements wobble when you're in the vicinity, and it freaks the fish out a bit, but only while it's going on. Overall, though, I'm very pleased with it.

I needed something that would help me easily clean my aquarium as it's over 2' deep and my pleco weren't keeping up. Looked around and this seemed to be the best product for its price. Good size and powerful magnet(watch your fingers). Used it on a 120G tank with 1/3" glass and worked great! Glass pad was needed as the blue acrylic pad was too soft. Takes a few swipes to clear thicker algae but not at all a hassle. Very easy to turn corners and switch sides. Haven't had any issues with the magnets detaching either.

Acuario de 45 litros y funciona muy bien. El imán es potente. Viene con dos tipos de limpiadores uno con una especie de fieltro y otro con un cepillo de finas cerdas

Si tienes plantas, piedras o adornos muy cerca de los cristales te costará limpiar o de plano no podrás sin destruir tu decoración, les doy un tip, pongan una fibra de estas verdes que se usan para lavar los platos por dentro entre el cristal y el imán, esto hace que se mueve más suave y no pegue los "brinquitos", en general bien, lo uso en dos acuarios con cristal de 9mm y todo bien, no flota lo cual es algo que no me gusta pero bueno, lo puedo pasar por el costo.

Tiene unos imanes potentes, y hace que limpiar el acuario sea mejor compré el mini aunque mi acuario es de cristal tendré que reemplazar después el material por el correcto
