What Are The Different Types Of Aquarium Filters?
Filters come in various kinds and have different working strategies; not every type is suitable for your tank, but only the one that fits its aquarium size, kind, pet, etc.
Below are the significant types of aquarium filtration systems:
Hang On Back (HOB)
This internal filter type is the best option for low-bioload aquariums but can also function satisfactorily in high-bioload. However, you cannot use this filter for huge aquariums.
This feature of powerful filtration makes it go deep into the tank and suck the water by filtering it through a filter media basket, then sends the filtered water back into the tank. The maintenance of these filter systems is super-easy.
These external filters typically stay below the tank's level and utilize siphon action to pull the water from the tank. Water passes through several levels to get cleaned and then returned to the tank.
As the name implies, these filters stay inside the tank, and you don't need to purchase any extra appliances to install them. These easy-to-install internal filters are equipped with an intake and an outtake compartment where water is getting sucked into the filter and restored.
Another filter type is sponge filters, which are cost-effective and support the mechanical filtration method. They offer a healthy atmosphere to the beneficial bacteria so they can colonize and support your aquatic pets. It is an easy and simple filter to keep the aquarium water clean and free from debris.
You can choose them if you have low-biological load tanks, but they are not very suitable for larger aquariums, so you can pick another filter type for much greater capacity tanks.

Buyer Guide: Factors To Consider Before Buying An Aquarium Filter For Large Tanks
Though we have chosen the best aquarium filters for you, don't worry if you are still not satisfied. You can explore the filters available in the market. However, when you are in the market, you might find many substandard products that can ruin your investment and waste your precious time - so you must keep the following factors in mind to make a hassle-free decision.
Always select a filter that will provide the maximum filtration media capacity for your large tank. Read the GPH of the filter on the box, and pick the best aquarium filter that provides more capacity than your tank needs. If you own larger aquariums and plan to install two filters, choose those with the exact GPH for the aquarium so that they will generate a current that is powerful enough for the marine inhabitants.
Stages of Filtration
Filters for large aquariums have different filtration stages: biological, mechanical, and chemical; but every filter doesn't create balance in these stages. Larger aquariums require a great balance between mechanical and biological filters but focus less on chemical filtration.
Biological filtration aids in maintaining your tank's bacterial balance, but this kind of filter demands more space. Mechanical filtration is necessary because larger tanks create more natural waste; if you don't have sufficient mechanical filtration, you must clean your filter. All-in-all, a pet owner is supposed to buy a filter for their lovely pets' tank that covers all these stages.
Cleaning a filter takes time, effort, and sometimes costs; this cleaning is not fun. So before deciding on a filter, you need to figure out how easy to maintain it is. You can prefer HOB filters since they are easy to clean and their filtration media are quick to replace; moreover, they don't need frequent cleaning.
Canister filters are also not hard to clean, but they are notorious as they demand your effort in opening and closing them.
There are different types of filters that you can buy according to the size of the tank and capacity. For larger tanks, canister and HOB (hang on back) filters are preferable. Submarine filters, under-gravel filters, and sponge filters are also some types, but they are not that powerful to deal with large tanks because they are not that powerful to cycle water. Ensure your filter is large enough to filter the water about four times the tank size within an hour.
Overpowered filtration has the drawback of sucking up things you don't want inside your filter. For example, if you don't have a protective cover, like a strainer, it may accidentally suck up aquarium substrate or small fish.
The Importance of Aesthetics
If you have adorable pets, then why not get them attractive accessories? So many tanks are aesthetic, well designed, and look elegant at home, so when you buy their accessories (lights, heater, pumps, filters), you also buy the appearance of their tank which should be aesthetically pleasing.
The price of the filter for your large tank depends on the size and type; aquarists need to spend between $30 to $300 to get one. However, a top-quality filter having exceptional features is also available for 50$, which will clean water speedily and work for years.
Frequently Asked Questions
This section will resolve the queries of pet owners with an aquarium that don't know which filter is best for them.
How Much Filtration Do Large Tanks Need?
As a rule of thumb, the filtration depends on whether the tank is lightly loaded or heavily loaded. A tank should have a flow rate of at least three times as large as the tank size; if you get filtration four times larger than the tank size, that is even better. Meanwhile, you must remember that your tank needs balanced filtration; over-filtration and under-filtration can harm your tank's inhabitants.
Is A UV Light Filter Essential For Clear Water?
UV filtration is helpful and valuable in various ways, as it cleans water and improves its clarity manifolds. Still, in many cases, it doesn't clear all the pathogens and bacteria that make the water cloudy. It depends on the size of your tank and type in many ways.
Which Is A Better Type Of Filter?
If you own a small and well-established water tank, sponge filters are the best option. Small filters require low water flow ,so sponge filters are preferable. But if we compare both, the power filter will lead the game as it is easy to maintain and delivers excellent chemical, mechanical, and biological filtration.
Is It Good To Have Two Filters In An Aquarium?
Typically, it is thought that more filters mean more water replenishment, more water clarity, and total clearance of all bacteria. Still, it is not always applicable and only for certain filters. However, most of the time, having two filters means none of the filters will perform better; the other way round, the chances are water will become recycled, which can be harmful to your pets and beneficial bacteria.
How Long Should I Keep My Fish Tank Filter On?
Fish are fragile; to keep them alive, you must keep the filters, lights, and air pumps on. However, if, in any case, you want to turn off the heaters, lights, or air pumps, you can do it for some time, but filters are supposed to remain turned on 24/7 - no compromise on them.
Filters are indispensable for an aquarium because, without filters, an aquarium is merely a box (perhaps a useless box) filled with water. However, installing a filter makes the aquarium super-beneficial for aquatic animals and plants. Keep in mind - every filter is not worth purchasing, but the one that is supreme in quality and a relevant filter for your tank size.
This article has reviewed a massive list of advanced and high-performing aquarium filters on the market that ensure the availability of good quality water. Delightfully, our narrowed-down list of revolutionary filters is innovative, easy to maintain, replace the filter, and clean. Still, our editors' best choices are the Polar Aurora Free Media 4-Stage Filter and Penn-Plax Cascade 1500 Aquarium.
