Understanding How Magnetic Algae Cleaners Work

We get it – most cleaning tools don’t require a masters degree in physics to understand how they work. But magnetic algae cleaners are a little different. In order to choose the best one for your needs, it’s important to understand how they work.

Put simply, magnetic algae cleaners use the power of magnets to remove algae from your tank walls. Typically, high-quality rare earth magnets are used in constructing these cleaners, consisting of an external and an internal piece. The internal piece comes with a sponge or scrubber attached, which is used to remove the algae from your tank walls.

The external and internal components come with powerful earth magnets, which attract and connect the two pieces. This allows you to easily move the internal piece around your tank without getting your hands wet. The scrubber side of the internal piece is what actually comes into contact with your tank walls and removes the algae.

This basic overview of how magnetic algae cleaners work should give you a good understanding of how they can be used to effectively remove algae from your tank. In the next section, we’ll discuss how you can pick the best one for your needs.

Buyers’ Guide: Factors To Consider When Buying A Magnetic Algae Cleaner

Now that you understand how magnetic algae cleaners work, it’s time to discuss how you can pick the best one for your needs. Learn how to make an informed decision by taking the following factors into consideration.

Tank Material

Small fish tank with cover

The first factor you’ll need to consider is the material your tank is made of. This is important because not all magnetic algae cleaners are compatible with all types of tanks. For example, if you have an acrylic fish tank you may need to purchase a different type of algae cleaner than someone with a glass fish tank.

Acrylic tanks are easier to scratch than glass, and frequent scraping with an abrasive magnetic algae cleaner can cause these scratches to become more visible over time. As a result, we recommend that you purchase an algae magnet that uses a softer material for its scrubbing pad. It’s hard to keep your acrylic aquariums completely safe, but you should still avoid using an abrasive cleaner if possible.

If your fish tank is made out of glass, you have a bit more flexibility when it comes to choosing an algae magnet. This is because tank glass typically comes with a coating that helps to prevent scratches, so you don’t have to worry about damaging your tank if you use a slightly abrasive cleaner. However, their thicker walls require stronger magnets, so make sure to keep this in mind when making your purchase.

Tank Shape

Strange as it sounds, the shape (and by extension, size) of your fish tank can also have an effect on which magnetic algae cleaner you should purchase. For example, curved edge tanks may require a different type of algae magnet than square edge tanks. Using an algae cleaner that’s too large and flat may result in layers of caked-on algae depositing in hard-to-reach corners.

Similarly, bowfront tanks may seem like some of the coolest fish tanks around, but they will require custom-made cleaners with adjustable handles for the curved aquarium wall. Otherwise, you’ll have to purchase a separate cleaner for each tank section. This is because the curved shape of bowfront tanks can make it difficult to reach all areas with a single algae magnet.

The tank shape factor is something that’s often overlooked, but it’s important to consider nonetheless. Given that uniquely shaped tanks are often used as display tanks, it’s even more important to use a high-quality algae magnet that won’t damage fish tanks with sensitive surfaces.

Magnet Strength

As we briefly alluded to in the previous section, magnet strength is another factor you’ll need to take into consideration. This is because different types of fish tanks require different levels of magnet strength in order to be properly cleaned. For instance, someone dealing with calcified algae would require a tougher magnet than someone who’s only dealing with a light film of algae.

Additionally, tanks with thicker walls will require algae magnet cleaners with stronger magnets. This is due to the fact that the algae magnet will need to be able to penetrate through a greater thickness of glass in order to make contact with the opposite side of the tank. If you have a thick-walled fish tank, opt for strong neodymium magnets, as they will be more likely to provide the level of power you need.

The difference between algae magnets may seem like a lot to take in, but once you get past the mumbo jumbo of rare earth elements and Gauss strength, it’s really not that complicated. Just remember to consider your tank type, the severity of your algae problem, and the size/shape of your fish tank. You’ll be sure to find one that’s perfect for your needs.

Accessories

In an increasingly competitive market, algae magnet manufacturers are offering more accessories to differentiate their products from the competition. As a result, you may find that some algae magnets come with replacement pads, additional brushes, or even a myriad of scraper blades for stubborn mineral deposits.

While these additional accessories may be nice to have, they’re not necessary for the average fish keeper. In most cases, a basic algae magnet with a few different types of pads will suffice. If you want a truly versatile tool, you can opt for something with a scraper attachment. These attachments are made of plastic or metal and are great for removing tough algae buildup.

Speaking from personal experience, I’ve found metal blades to be an unexpected godsend. A stainless steel razor blade attachment can be used to scrape away tough deposits of calcium and other minerals that often build up on glass aquariums. This has been an invaluable tool in my never-ending battle against hard water stains.

Ease of Use

Last but not least, we come to the most important factor: ease of use. Regardless of how good an algae magnet is, it won’t do you any good if you find yourself fiddling with awkwardly designed long-handled scrubbers or a handle that’s prone to slipping out of your hands. When dealing with algae in fish tanks, you want something that gets the job done with minimal fuss.

Generally speaking, an outer magnet with an ergonomic handle or a non-slip grip will make a world of difference. As for the inner magnet, you want something easy to remove and clean. All the additional features in the world won’t make up for a magnetic fish tank cleaner that’s a nightmare to clean. How else would you be able to reuse it?

At the end of the day, the best algae magnet is the one that gets the job done without any headaches. With that in mind, let’s look at some of the best magnetic algae cleaners on the market.

7 Best Magnetic Algae Cleaners For Glass And Acrylic Tanks

Now that you have a better understanding of what to look for, it’s time to take a closer look at some of the best magnetic algae cleaners on the market. We’ve scoured the internet and compiled a list of seven of the best magnetic algae cleaners you can buy.

1. NEPTONION Magnetic Aquarium Algae Scraper

NEPTONION Magnetic Aquarium Fish Tank Glass Algae scrapers Glass Cleaner Scrubber Clean Brush
  • Product Dimensions: ‎ 2.8 x 1.5 x 2.4 inches
  • Product Weight: 3.53 Ounces
  • Manufacturer: ‎ NEPTONION

The first entry on our list of recommendations is a tried-and-true product that aquarium enthusiasts have used for years. The NEPTONION Magnetic Aquarium Algae Scraper is one of the market’s most thoughtfully designed algae scrapers. This algae scraper comes in several sizes, allowing you to find the perfect fit for your aquarium.

As a testament to its ergonomic design, the non-slip handles make it easy to grip and maneuver, even when your hands are wet. Plus, the scraper floats to the surface after you remove the external sponge. Those days of sticking your arms into your tank are over! Lastly, the sponges do not scratch the glass, making this one of the safest algae scrapers for your aquarium.

If you’re looking for an algae scraper that will make your life easier, this two-part magnetic scraper is the way to go. However, some reviewers note that the magnet can become detached from the handle after extended use. Otherwise, this excellent product will make short work of even the most stubborn algae.

PROS

  • Ergonomic design
  • Non-slip handles
  • Floats to the surface
  • It comes with a scratch-resistant sponge

CONS

  • The magnet can become detached from the handle over time

2. Aqueon Algae Cleaning Magnet

Aqueon Algae Cleaning Magnet
  • Manufacturer: Aqueon
  • Dimensions: 4.5 x 2.5 x 0.6 inches
  • Aquarium Type: Freshwater, Saltwater
  • Fish Type: Tropical Freshwater, Marine Fish
  • Material: Plastic

When it comes to reputable manufacturers, Aqueon is at the top of the list. This company has a long history of producing high-quality products, and this algae cleaning magnet is no different. At first glance, you’ll notice the sleek, modern design. But upon closer inspection, you’ll see that this magnet is built to last.

The Aqueon Algae Cleaning Magnet has both an abrasive pad for stubborn algae on sturdy surfaces and a gentler scrubbing pad for acrylic tanks. The inner cleaning magnet sinks to the bottom of the tank when the external magnet becomes separated, making it easy to retrieve in the event that it falls in.

While this algae magnet is versatile and effective, some reviewers caution against using it close to gravel or substrate. Bits of substrate may become trapped between the magnet and the glass, causing scratches on delicate surfaces such as acrylic tank walls. Be sure to leave at least an inch of space between the magnet and surfaces that you don’t want to risk scratching.

PROS

  • Comes with an abrasive and a gentler scrubbing pad
  • Inner magnet sinks to the bottom of the tank
  • Aesthetically pleasing design
  • Strong magnet for effective cleaning

CONS

  • Don’t use it close to gravel or substrate to avoid scratches

3. Mag-Float Acrylic Floating Magnetic Aquarium Cleaner

Mag-Float Glass Floating Magnetic Aquarium Cleaner
  • Dimensions: 4 x 1.8 x 1 inches
  • Aquarium Type: Freshwater, Saltwater
  • Fish Type: Tropical Freshwater, Marine Fish

Mag-Float is widely regarded as the granddaddy of aquarium cleaners, and this floating magnetic algae brush is one of the company’s most popular products. As the name implies, this algae brush floats on the surface of the water, making it easy to retrieve if it becomes separated from the external magnet. I personally don’t like to get my sleeves wet, so this feature is a true godsend!

The nerds out there will be thrilled to learn that Mag-Float uses rare earth neodymium magnets, which is widely considered the strongest type of permanent magnet. This gives the Mag-Float superior cleaning power, making it ideal for larger tanks with thicker algae growth. Unfortunately, this does make the Mag-Float less ideal for acrylic tanks, so keep that in mind before making your purchase.

For glass tank aficionados, however, the Mag-Float is simply the best of the best. If you want an algae brush that will make short work of even the most stubborn algae, this is the one you want. Pricey as it may be at $22 for a medium-sized brush, the Mag-Float is definitely worth the investment.

PROS

  • Floats on the surface
  • Uses rare earth neodymium magnets
  • Superior cleaning power

CONS

  • Less ideal for acrylic tanks
  • Pricey

4. Carefree Fish Aquarium Mini Super Magnetic Cleaner

If you’re like me and you’re always on the lookout for a great deal, then you’ll love the Carefree Fish Aquarium Mini Super Magnetic Cleaner. This little guy is only $9.99, making it one of the most affordable options on the market. Tiny as it may be, this magnetic algae scraper is still mighty, thanks to its super-strong magnets.

Plus, the fact that it comes with great rubberized grip means that you won’t have to worry about it slipping out of your hands and into the tank.

The only downside to this algae brush is that it won’t clean sharp edges or corners as well as some of the rectangular options on the market.
