How to Choose an Algae Scraper

When choosing an algae scraper, the question you need to ask yourself is not “What is the best” but “What is the best for my tank?”. This depends on two factors: The material of the tank and its size.

What’s Your Tank Made Of?

Some scrapers or scrubber pads are suitable for glass tanks, others are made for acrylic tanks, and some have options to be used for both.

What’s the difference, you may ask? In the case of a glass tank, the scrubber pad is made of a harder, tougher material, like Velcro’s hook side. While in the case of an acrylic tank, the scrubber pad’s material is softer, like the loop side of Velcro, to prevent scratching the acrylic.

As for scraper blades, metal scrapers are used for glass tanks, and plastic scrapers are used for acrylic tanks. Using a material intended for a glass tank on an acrylic one will cause the most unsightly scratches that are mostly irreversible.

Pro Tip: scrapers used on glass would scratch an acrylic tank; do not ever use a hard scraper on acrylic.

When it comes to cleaning the front of an acrylic tank, your best bet is to get Original Mr Clean Magic Erasers, the kind that doesn’t have any added cleansers. Just wet and squeeze your magic eraser and prepare to get the cleanest surface!

    Tank Size

    A scraper that works for a 100-gallon tank is probably WAY too huge for a 10-gallon; it would take you forever to scrape all the algae in a 100-gallon with a little scraper meant for a 10-gallon; bottom line, get something appropriate to your tank.

    If you’re considering a magnetized scrubbing pad, the thickness of the tank walls is very important. A bigger tank with thicker walls will need a stronger magnet than a smaller one with thinner walls. 

    If you have a large tank and get a scrubber pad with a magnet that isn’t strong enough, it may attach securely, but it will surely not exert enough pressure to do the cleaning job.

    Another tip is to consider some long-handled tools for reaching algae at the back or the deep bottom of a large tank.

    7 Best Algae Scrapers Reviewed

    Now let’s take a look at some of the most efficient scrapers for each tank size.

    1. Neptonian Magnetic Aquarium Glass Algae Scraper >20 Gallon Tank (76 Liters)

    It is important to note that this scraper is suitable only for glass fish tanks but not acrylic ones. It features two magnetized halves that stick to each other, one on the tank’s outer wall and the other on the inside wall. 

    The scrubber side is made of rough fabric with tiny hooks that efficiently scrape off any algae without scratching the glass. The other half, which sticks on the outside, is covered with felt which allows for smooth gliding when you’re cleaning your tank. 

    Add to this the ease and comfort of using a large non-slip ergonomic handle, and you will find that cleaning your tank has never been easier, which will make you less likely to ignore it!

    A cool thing about this scraper is that if the two halves get separated, the half on the inside will float right up to the surface of the water. So, you won’t have to reach into the tank to grab it, wetting your hands and probably your sleeves in the process and endangering the water’s quality.

    Worthy to say is that the magnet strength is pretty good, which means that this won’t happen much and also guarantees proper cleaning. What more can we ask for? Well, they offer larger sizes for bigger tanks, too! It seems that this scraper has got it all covered.

      2. Petacc Double-Sided Fish Tank Cleaner Sponge >20 Gallon Tank (76 Liters)

      This simple, old-school algae scraper is suitable for all kinds of tanks, whether acrylic, glass, or plastic.

      The brush head is made of a high-end double-sided sponge that is tough and durable. It cleans the tank easily without scratching the walls.

      It has a non-slip plastic handle that offers a comfortable grip and a 45-degree tilt that makes it easy to reach every corner of a 20-gallon tank. There is also a hole on the handle’s end to enable you to hang it on the wall between cleanings.

        3. MiguCo Stainless Steel Algae Scraper With 10 Blades – 30-40 Gallon (113-151 Liters)

        Since this scraper is made of stainless steel, don’t think about using it with an acrylic tank. Like we have previously mentioned, tougher materials are only appropriate with glass tanks.

        That said, this scraper is very durable and is anti-rust (In freshwater). It is provided with ten extra razor blades that are very easy to change and are very efficient at scraping even the most resistant types of algae, like the dreaded green spot algae.

        It features a long handle, and there is also an extension rod, so you’ll be able to reach the deepest ends of your tank without getting wet. With a right-angle blade design, the corners of your tank will also be easily accessible.

        Here are some extra tips to keep in mind:

        •  Clean the tank from the bottom to the top in a pulling motion. Also, make sure to get all the algae and any debris out of the tank with every scrap, or else the material will be left hanging in the tank, contaminating it, which is really the opposite of what we’re willing to do!
        • Wash the razors with water after use, and don’t cover them until they dry.

          4. Hygger Carbon Fiber 6 in 1 Aquarium Cleaning Tool Kit Algae Scraper – 30-40 Gallon (113-151 Liters)

          Let’s start by saying that this is not your average tank cleaning kit. This multi-purpose tool kit will efficiently and professionally help you clean your tank and provide a healthy aquatic environment for your swimming pets. With a telescopic handle and interchangeable heads, this tool is simply 6 in 1. 

          The handle is made from carbon fiber composite, which is both durable and lightweight. It extends from 19.7ft to 35.4ft and offers a secure attachment to the interchangeable heads via spring notch closure. So, it’s safe to say that those heads are never falling into the water after assembling them, which is also quite an easy job.

          By now, you are surely wondering what all those different heads are for. Let’s take a look:

          • Flat sponge: It is used for cleaning the glass and the substrate. Different parts of the tank are made accessible by its 90 degrees rotation.
          • Right-angle sponge: Very effective in cleaning hard-to-reach spots and under the rims.
          • Razor blade: Perfect for scraping more stubborn spots. It is anti-rust, even in salt water, and has a cover to protect you from getting hurt.
          • Tube brush: Very handy for cleaning pipes and hard-to-reach areas.
          • Gravel rake: It is used for raking the soil and cleaning the gravel.
          • Fish net: Appropriate for cleaning debris as well as catching small fish.

          Pro Tip: Always move the flat sponge and the right-angle sponge in the same direction while cleaning. Also, be sure to wash the razor blade after use and wait till it has dried before covering it.

            5. Mag-Float-30 Small Glass Aquarium Cleaner – 30-40 Gallon (113-151 Liters)

            The Mag Float is the classic magnetic tank cleaner. It can be used for glass and acrylic tanks up to 30 gallons in size. 

            Like the Neptonian Magnetic Scraper discussed before, it is also made of two halves, and the half that is submerged in water floats up if it is separated from the other half.

            The magnets are high-quality neodymium rare earth magnets that will not lose strength over time and ensure sufficient pressure that is necessary to clean the walls.

            Although the handle isn’t ergonomic, it is solid and easy to use. The scrubber pad’s large surface area also makes cleaning fast and efficient, and its material ensures that debris won’t stick to it. It also features an optional scraper blade attachment for more resistant algae, but you need to be aware that this item is sold separately.

            While this scraper is perfect for cleaning the front and side walls of your tank, it will not reach the back of the tank.

              6. Fl!pper Max Float – 2-in-1 Floating Magnetic Aquarium Glass Cleaner – 55 Gallon (208 Liters) +

              Scrub, flip, scrape, and float, the Fl!pper has got it all! Why is it called “Fl!pper”? Because it flips between scrubber and scraper by simply twisting the outside handle without getting wet.

              Like all magnetic cleaners, it comes in 2 halves; one sticks to the outside of the tank wall, and the other sticks to the inside. The inner half has two sides. One side is a soft cleaning and polishing pad that is good for removing soft algae, while the other side is a hard rust-resistant stainless steel scraper that works wonders on hard algae.

              The blade has only 3 contact points, but what’s the significance of this? It ideally results in a safety gap between the cleaner and the glass, thus lowering the chances of trapping sand. So you will get an efficient cleaning and avoid scratching the glass even if you’re cleaning below the sand.

              It’s made with rare earth magnets with high durability and superior strength that guarantees efficient cleaning. While this means that the two halves will hardly detach, if they do, the unique buoyancy feature will keep the magnets facing each other for easy retrieval.

              The Fl!pper is suitable for glass or acrylic tanks and can be used in fresh or saltwater. It also comes in 3 different sizes, nano, standard, and max, with the latter being ideal for bigger tanks.

                7. JZMYXA Aquarium Fish Tank Clean Set – 55 Gallon (208 Liters) +

                This tool features an extendable handle that goes from 1.8ft to 2.6ft, making it ideal for bigger tanks, whether acrylic or glass. Multiple attachments for multiple purposes can be easily assembled and disassembled from the handle with a strap. 

                If you decide on this set, you’ll be getting an algae scraper, a flat sponge, a fish net,  a spoon net, a plant fork, and a gravel rake.

                While the flat sponge is excellent for cleaning softer algae, the scraper will come to the rescue when more resistant algae are at hand. The spoon net does a great job at catching any floating objects in the aquarium, and the plant fork will allow you to easily extract aquatic plants without much disturbance to the environment. 

                The gravel rake can be used to clean the sand and gravel and rearrange them as you see fits. With all these attachments, there is hardly anything that you’ll be missing in your cleaning process.

                  Which Algae Scraper Is Best?

                  Choosing the best scraper ultimately depends on the size of your tank. While there are many options out there, a few do seem to stand out.

                  I am definitely impressed with the FL!IPPER magnetic cleaner. The scraper side of the inside magnet would definitely cut down on cleaning the front glass of a big tank.

                  The MiguCo Stainless Steel Algae Scraper is a great old-school metal scraper that could be great for getting off the tough stuff, like stubborn green spot algae. This design of algae scraper has been around for decades for a reason: it works.

                  For smaller tanks, you can probably get away with using something like the Petacc Double-Sided Fish Tank Cleaner Sponge for the life of the tank. I have a similar scraper that I’ve had for years and years.
