Types of Algae Scrapers and Glass Cleaners

An algae scraper is a device used to remove algae from an aquarium glass. Many different types of algae scrapers and glass cleaners are available on the market, each with its unique set of features.

The most basic type are handheld scrapers, a piece of plastic or metal with a sharp edge. These are the least expensive and most basic type of algae scrapers but lack the degree of customizability seasoned aquarists prefer. More expensive versions come with various attachments, including a plastic scraper attachment that’s gentler on acrylic surfaces and a stainless steel scraper attachment for tough layers of algae.

If conventional scrapers aren’t for you, consider an algae scraper brush with cleaning pads. These cleaning brushes are typically made of nylon or polyester and are designed to clean stubborn algae off aquarium glass without scratching. You may need to go through some trial and error to identify a scraper brush suitable for your aquarium, as some are too stiff and can damage soft corals, while others are not stiff enough and won’t do a thorough job of cleaning.

Another type of algae scraper that’s becoming increasingly popular is the magnetic algae scraper. Magnetic cleaners rely on two magnets, one of which is attached to the outside of the aquarium glass, while the other is attached to a piece of flat sponge or other material. As the stronger magnet on the outside of the aquarium is moved, the sponge follows and scrubs away algae in its path.

Choosing The Right Tank Scraper: Buyers’ Guide

No matter which type of algae scraper you choose, it’s important to get one that’s right for your needs. Here are some factors to keep in mind when shopping for an algae scraper or glass cleaner:

Tank Size and Shape

The first thing to consider is the size and shape of your aquarium. A larger aquarium will benefit from an adjustable length scraper that can reach all areas of the tank, while nano tanks can get by with a shorter, fixed-length scraper. Curved surfaces require a curved scraper head to clean properly, while flat surfaces can be cleaned with any simple tool that can reach all areas.

The shape of your tank also affects its wall thickness, which is important to consider when choosing a magnetic algae scraper. Keeping your fish tank clean requires a magnet that can attach securely to the outside of the glass, so make sure to check the specifications of your chosen product to ensure it will work with the thickness of your aquarium glass.

Generally speaking, most aquarists benefit from a versatile algae scraper that can be used on various surfaces. A good all-purpose aquarium glass cleaner will typically have both a plastic and metal scraper attachment and a brush attachment for tougher jobs. Some will even come with a sponge for substrate cleaning, making them true all-rounders.

Algae Type

The type of algae you’re dealing with can also affect your decision. Brown algae, for example, can be quite stubborn and may require a stiff-bristled brush to remove. Green algae, on the other hand, is much softer and can usually be removed with a soft-bristled brush or even a simple plastic scraper.

Generally speaking, soft algae such as blue-green algae and black beard algae can be removed with a soft-bristled brush or a plastic scraper, while tougher algae such as green spot algae and red slime algae require a stiff-bristled brush or a metal scraper. Unsightly algae may be a nuisance, but it’s important to remove it carefully to avoid damaging your aquarium glass or decorations.

Getting rid of unwanted algae is a matter of getting the right tool for the job, so you want to make sure that you let algae type be a factor in your decision. After all, there’s no point in buying a powerful metal scraper if all you’re dealing with is some soft green algae!

Abrasiveness

A strong scraper may seem like the be-all and end-all of aquarium glass cleaning, but it’s important to consider the abrasiveness of your chosen tool. Abrasive materials such as metal or a sharp blade can wreak havoc on most acrylic aquariums, and may even damage some types of glass surfaces. A perfect cleaning job should leave your aquarium looking as good as new, so you don’t want to risk scratching or marring the surface with a too-aggressive algae scraper.

Generally, a glass aquarium can handle a metal scraper without issue. Still, using a purpose-built acrylic scraping blade or a soft-bristled brush with a quality sponge on an acrylic aquarium is best. These days, you can even find an acrylic blade explicitly designed for use on delicate surfaces, so your options truly are endless!

Of course, complete cleaning remains important, but you also don’t want to do more harm than good in the process. An overly-abrasive aquarium cleaner can damage your aquarium’s surface, so even if you own a glass fish tank, it’s best to consider the type of algae you’re dealing with before making your final decision.

Handle Design

One important but oft-overlooked aspect of algae scrapers is the handle design. A good algae scraper should have a non-slip handle design that’s comfortable to grip and easy to control. After all, you don’t want your aquarium brush or scraper slipping out of your hand in the middle of a tough cleaning job!

On top of a non-slip handle surface, you also want to look for ergonomics. For instance, a chunky handle with comfort grip can help to reduce fatigue during extended cleaning sessions. There’s even a specific type of scraper with a hollow design that can be filled with water to add weight and increase scrubbing power – perfect for those tough jobs.

The best algae scrapers will have a comfortable, ergonomic handle that’s easy to grip and won’t slip out of your hand, even when wet. For maximum durability and versatility, you should also look for a model with a telescoping handle and one that can handle being immersed in saltwater aquariums. These features will make your algae scraper an invaluable tool that can be used for years to come.

Reusability

Last but not least, a quality product is designed with durability and reusability in mind. After all, you don’t want to replace your algae scraper every few months! For instance, a good algae scrubber will be designed with a hyper-durable piece of extension rod that can be affixed to a myriad of replacement sponges and used for years to come.

Under some circumstances, you may need to rely on manufacturer-specific replacement parts to keep your scraper in top shape. However, these should only be viewed as a last resort – after all, who wants to have something with special plastic blades if there are more versatile options available? Ideally, you should be able to find your removable blades easily – no matter what type of algae you’re dealing with.

Of course, reusability also depends on how easy it is to keep your brush head clean, or slip your brush pad out for a thorough cleaning session. A good-quality algae scraper will be easy to disassemble and clean because even scrapers used on the cleanest freshwater aquariums can start to harbor bacteria over time.

Selecting the best algae scraper for your needs doesn’t have to be rocket science – but it is important to consider the type of aquarium you own, the type of algae you’re dealing with, and the handle design that will work best for you. With a little bit of thought, you can find an algae scraper that will make short work of even the most stubborn algae growths – without damaging your aquarium in the process!
