Marineland Magniflow Canister Filter

Whether you have a saltwater aquarium or freshwater aquarium, you’ll want a good canister filter to keep your tank crystal clear.

The filter is ideal for both freshwater and saltwater setups, and is suitable for tanks from 32 to 60 inches in diameter.

This ensures that the device will work as fully as possible. It also has a quick prime button to start the system up automatically.

One of the most important factors to consider when choosing a canister filter is the GPH rating of the device. The rating measures how much water is processed in an hour. This is important to determine whether or not the filter is able to handle your tank’s needs.

Biological filter media remove harmful toxic elements from the tank water, allowing essential bacteria to grow. These media are usually located at the bottom of the filter. They help convert ammonia into nitrite. They also eliminate fine debris. It is also important to make sure that the filter media is salt proof. If the filter media is not salt proof, it may be poisoning the aquarium’s water.

Another important factor to consider is the price. A cheaper canister filter may not have salt proof parts, or may have metal parts. It is also important to keep in mind that cheap filters can leak, or have other defects. You should also consider the physical size of the filter, how easy it is to clean, and whether or not the filter comes with a warranty.

The Marineland Magniflow canister filter offers complete three-stage filtration. This includes a sponge that contains beneficial bacteria. The water then passes through a polishing chamber, which helps remove dirt and fine particles. It then returns to the tank through a tube.

Product Selection Criteria to Consider


Unlike mechanical filters, which only trap solid particles in the water, chemical canister filters can be configured to provide both mechanical and chemical filtration. This means that you can customize the media that you use to filter the water in your aquarium.

Chemical filtration is a process that uses specially formulated chemical additives to dissolve impurities and pollutants in the water. These additives remove heavy metals, dissolved organics, and other pollutants from the water.

Chemical canister filters for aquariums come in a variety of brands and materials. They can remove pollutants like nitrates. These filters come in different shapes and sizes, and can be configured to filter a large amount of water. They are usually very efficient filters. However, they can be very expensive.

The most common type of chemical canister filter for aquariums is activated carbon. Activated carbon removes dissolved chemicals and odors from the water. It is also effective at removing other contaminants like trace elements and medications.

Another type of chemical canister filter for aquariums uses zeolite to replace sodium in the tank water with ammonia. Zeolite has hundreds of tiny pores, which allows the exchange to occur. This process continues until the zeolite no longer contains sodium.

While carbon is the best known chemical canister filter for aquariums, there are many other types of chemical filtration media. Some are better than others.

These include peat granules, activated carbon, and nitrate absorbing media. Each has its own benefits. They can remove dissolved chemicals and odors, and can also help clear up algae problems. Some canister filters include a zeolite and activated carbon combo, or can be configured with multiple media types.


Biological canister filters for aquariums offer superior biological filtration for your aquarium. These filters use a process called the nitrogen cycle to break down ammonia, nitrite and nitrate. These wastes are very harmful to fish.

The water in your aquarium is drawn into the canister through an intake pipe. This water then flows through the filter media. The water is then pumped back to the aquarium through the return pipe.

The water then passes over colonies of bacteria that break down ammonia and nitrite. This cycle can take place in a variety of different ways. Some filters use a spray bar to agitate the surface of the media. Others use fine floss or floss-like beads.

The bacteria that break down nitrate grow best in oxygen-rich water. They are less toxic than ammonia and nitrite.

Biological canister filters for aquariums have two basic types: plastic and ceramic media. Plastic media is often used in the final stage of the nitrogen cycle. This media is reusable, but must be replaced regularly. The cost of these filters ranges from about $8 to $60.

Biological canister filters for aquariums can come in many different styles. Biological filters usually have a layering of different filter media types to maintain good water quality. The density of the media determines the size of particles filtered.

Biological canister filters for aquariums can also be internal or external. Internal canisters fit inside the tank, while external canisters are typically positioned below the aquarium.

In addition to biological canister filters for aquariums, you can also choose chemical and mechanical filtration systems. These filters use a variety of media types to remove dissolved pollutants and particulate matter.


Traditionally, canister filters are used in mid-size and large aquariums. They offer superior filtering and are usually installed beneath the aquarium. They also offer great flexibility in water pick-up. They are also quieter than air-driven in-tank filters.

There are three main types of canister filters. The first is the internal canister, which is essentially a plastic cylinder. It fits inside the tank and can be used for biological or mechanical filtration. Some models come with inline heaters.

The second type of canister is the external canister. These filters are based on the HOB design, but are more flexible with their media selection. They are also a lot more expensive than the internal types.

They are also a lot more complicated. Canister filters can be very expensive, but they provide superior filtering power. They are also more user-friendly than HOBs. They can be reconnected to the aquarium for cleaning and maintenance. Some models include an inline heater and UV sterilizer.

Some of the latest canister models offer a range of media options, making it easy to customize the water pick-up, flow rate, and media type for your aquarium. The media can be layered in different ways to ensure excellent water quality.

The simplest DIY internal filter requires a container and pump. A few more advanced models feature special treated pads for chemical and biological filtration.

Canister filters have long been a staple of the hobby. Although they are more expensive than other types of filters, they are very reliable and can last for years. They are also a lot more user-friendly than the old-school HOB models.

Regardless of the type of canister filter you choose, remember to clean the media regularly. This will increase nitrogen waste handling capacity, and will help improve the clarity of your aquarium.
