 Types of Fish Tank Filters

Here are the different types of fish tank filters you can expect to find on the market.

Air-driven internal fish tank filter

These filters are small, making them great for compact aquariums kept in a hospital or home. Their size makes them suitable for easy integration with a wide variety of fish tanks.

Even though they are small, they can still be very sturdy and well constructed. It will help to keep your small aquarium inhabitants healthy and free from any harm in the water.

Undergravel filters

These filters are placed in the bottom of the fish tank underneath a layer of aquarium gravel. They move the water through the gravel to create conditions for biological filtration to occur, where beneficial bacteria break down the wastes in the fish tank.

Although the filters are designed primarily for biological filtration, some models also have replaceable cartridges. These cartridges have activated carbon to help with chemical filtration.

Power filters

Power filters are a type that is widely used in many aquariums. They are relatively easy to set up and last for a long time. Many people love them, as they provide the best performance for biological, mechanical, and chemical filtration.

They are designed to easily hang on back of the aquarium for convenience, and can be used for many different types of fish tanks. The replaceable filter cartridges make maintenance very easy, as compared to other types.

Canister filters

The canister filters offer all the functions you need in a fish tank filter. You can expect them to deliver on all fronts—mechanical, chemical, and biological functions.

The body, which is often called the canister, is significantly larger for these filters than it is for other types of filters. Each canister will have locations to hold each different type of filter media, and the large canisters will have more filter media. This type of filter does take more effort to set up and maintain, in exchange for its power and flexibility.

Wet/Dry filters

These are known to be the best in biological filtration. They are designed to be a great fit for saltwater aquariums that demand effective biological filtration.

These filters get the name “wet/dry” because the filter media can be exposed to both air and water. This type of filter, in general, will help to increase the beneficial bacteria that lead to effective processing of waste materials.

How to Choose the right Aquarium Filter?

With the following considerations, you should be able to make the right decision and buy the correct quiet fish tank filter for your aquarium.

Recommended Aquarium Tank Size

Not all filter systems will work with all the tanks. Some have the capability to handle more than one tank size, but others will be fixed.

The manufacturer will always indicate the recommended tank size in the description. Once you have the right fish tank size in mind, it should be easy to make a decision on the filter system to buy.

The Filtration Technology

The filtration technology will differ from one brand or model to another. Each company always wants to be rated as the best, depending on the filtration technology.

This will prompt some companies to come up with a number of “best features” they could use for filtering the water, and some methods might not be suitable for all types of fish tanks. Take the time to learn about the different filtration systems and see what works for your current fish tank.

Water-Flow Rate for The Filter

The water flow rate is measured in gallons per hour. You want a filter that will fill your fish tank faster. Research to find this rating before making the purchase.

It is better if you can compare different brands to see which offers the best water flow rate. Some brands will have a higher flow rate than others do, so always choose wisely among competitive brands.

Fish Tank Filters Brand

Brands matter a lot when choosing the right fish tank filter for your aquarium. Some brands, like the ones mentioned above, are known to offer more sustainability than the others.

Using products from a brand should be a sure way of knowing that other products of the same brand will work effectively. Such top brands include companies such as Fluval, Penn Pax, and many others.

Sometimes it is easy to find the top-rated brands by sorting the products by rating. This will give you the best products that are seen to deliver according to user needs.

The Fish Tank Filters Reviews

Any filter review will help to identify a good fish tank filter that you need for your aquarium. Some filter manufacturers might exaggerate the filter features that do not end up meeting the user needs.

From the reviews, you can know more about the filter and decide whether it works for you or not. Some of the users of such filters will offer useful information on helping other users to identify the best filters in the market.

Make sure that you read the reviews from top rated stores and review sites as a way of finding honest reviews about the products.

Conclusion

As you can see, several things actually affect how the filter will work. There are new models coming to the market each other day, so make sure that you can choose the right type that works for your pet care model. The design is quite important, as it will determine if the product can fit in your aquarium or it can be adjusted for a perfect fit.

Set up and installation process is sometimes a deciding factor. Sometimes it is hard for new users to operate the filters even with manuals supplied by manufacturers. If the product is designed to easily fit on the fish tanks, it should be easy to set up and install. Now that you know more about the best fish tank filter systems, you can choose the correct one easily.
