Having a small aquarium that fits in your home is fun. It will not take too much space in the home, and you still get to have fish in the tank. The only issue comes in if you have no ideas which filter to use. Getting the wrong filter might hurt your fish or create a mess in the room. As such, you need to know how to choose the right filter for your 30-gallon aquarium.

One of the features we looked at is how powerful the filter is. When owning a filter, you must know it can get the job done. The flow rate will affect how well your filter works. It will also ensure that you do not have to worry about needing to get a replacement soon enough. The flow rate also determines the fish you get to keep. If you have a very powerful filter, then you need to keep bigger fish, so they do not get harmed in any way. Another feature we looked at when choosing the best filters for a 30-gallon aquarium is the additional features like multi-filters and the quietness of the filters. All these go a long way to ensure that you have a functional filter. If you have no idea what to look out for in a filter, look no further. Here are the top filters in the market and why they would work for you.

AquaClear Fish Tank Filter

Features
  • Flow rate: 150 GPH
  • Size: 4.5 x 8.2 x 6.7 inches
  • Filtration: 3-stage
  • Tank capacity: 10-30 gal

More features: Easy to install, the optimal mechanism

The Aquaclear Fish Tank Filter stands out because it efficiently cleans out debris. It has a three-stage filtration system that ensures all the debris is cleaned out. It is also very powerful, so you can be sure no dirt or dust will be left behind. Most aquariums with bigger fish find it very efficient since you do not have to clean out the tank every so often.

We gave this filter the editors’ award due to its overall performance. The filter pump is powerful enough, so the entire tank will be cleaned. You do not have to worry about getting back to clean it. We also love that it has 3-stage filtration, which most filters in the market lack.

The AquaClear fish tank comes with activated carbon, different from the AQUA-TECH Power Aquarium Filter’s carbon surface. As such, you get better quality water in the long run. The activated carbon is made of superior quality, which makes the filtration process even better for you.

What are its best features?

  • It is powerful enough to clean the entire aquarium
  • It has two-stage filtrations

What could be improved?

  • It is loud
  • The current is too powerful for smaller fish

Features

  • Size: 12.2 x 7.9 x 6.1 inches
  • Filtration: 2-stage
  • Tank capacity: up to 30 gal

More features: ultra-quiet, flow regulation handle, filter basket, UV sterilizer

The one thing you will notice with this filter is it has premium quality features. Aside from having a powerful filtering feature, it also has a UV bulb feature that helps kill bacteria in the water. The filter is quiet yet so powerful, and most people like it because of this. If the bulb gets spoilt, you can always replace it since that is no big deal.

We chose this as our premium filter because of how great it is for working. It can be used in an aquarium in your bedroom because it is quiet. We also love that it can be used with a bigger aquarium even though it is meant for the 30-gallon size.

Compared to the AQUA-TECH Power Aquarium Filter, the only difference is that it does not have a carbon surface. As such, one will not get the perks the layer of carbon comes with. Most users prefer Aquatech because of the carbon, although the UV light feature in this filter still makes it stand out.

Why did it make our list?

  • It is quiet
  • It comes with the UV light feature

What is not ideal about it?

The Marineland Penguin 200 is a great filter if you need powerful suction. The multistage filtration makes it easier to use since it removes all the debris from the aquarium. While some people think it can be loud, you must ensure you read the manual and set it up well. It runs with a very low hum after proper installation. You will not even realize it is there in the first place.

We love this filter because, based on its price, you will get value for your money. It is powerful and has a bio-wheel that helps with wet and dry biological filtration. We also love that it has multi-filtration, which ensures that the water in your aquarium stays clear.

The only difference this filter has with the AQUATICLIFE 115 Mini Internal Protein Skimmer/Filter is its difficulty installing it. Most users have complained that the Marineland filter can be hard to use because it is complex to install. Needing that extra help can be costly, and most people do not want to pay that price. Once you get it installed, however, you can be sure you’ll get value for your money.

Most people find it easy to assemble and disassemble, making it perfect for those times when you need to change a few changes to your filter.

We love this filter because it is submersible. It reduces the sound of flowing water in the house, so you won’t have to bear with the filtering noise. It also has different noddle lengths and sizes, and you can use this based on the kind of aquarium you have.

When compared to the AQQA Aquarium internal filter, which is submersible, you get better features with the No17. It has nozzles that can be adjusted based on what you want them to do.

Things to Consider

Buying a filter can be daunting, especially if you do not know what you need to look out for. To help you decide, we have written a buying guide. We have also included a few features you need to look out for when choosing the right filter.

Important Features

There are several features you need to consider when choosing the right filter. Top of the list is the type of filter, the noise rate, the flow rate, the tank size, and the installation process. Let’s take a detailed look at how these features affect the quality of the tank.

Type of filter

10 Best Filters for 30-Gallon Aquarium: Perfect Capacity for Medium-Sized Tanks! (Fall 2022)

Knowing what design you need goes a long way to ensure you have a filter you can use.

The one thing you need to consider when buying a filter is the kind you buy. Brands are different, and they will all have different perks. For instance, the Fluval C2 Power Filter can be used for fresh and salty water, while the AQUATICLIFE 115 Mini Internal Protein Skimmer/Filter is only fit for salty water. Such things might seem trivial, but they will go a long way in ensuring you get a filter that works for you. It also helps if you know whether your filter is submersible or not. Submersibles like AQQA Aquarium Internal Filter are preferred because of how efficient they are when it comes to reducing the sound of water passing through them. They also work best with smaller tanks.

Flow rate

The flow rate affects how fast a dirty aquarium can get cleaned. It also affects how much force your filter produces when it is working. If you are unsure of all this, you might end up harming your fish. Filters like AMOSIJOY Canister Filter have adjustable flow rates, making it easier for you to choose a filter that works with your aquarium. You will not have to worry that your fish will not be okay.

Filtration

The main reason you pick a filter is to filter out all the debris that builds up in the water. As such, getting a quality filter beats the whole point of wanting to filter your aquarium in the first place. To help ensure all the debris is out of the water, most people use filters like Aqueon QuietFlow have multiple stages of filtration. They work best because one does not have to worry that the water will still have debris. If you have a bigger aquarium, you might also consider getting a filter like NO.17 Submersible Aquarium Internal Filter that works with different size aquariums. That way, you have something that works perfectly for you.

Tank capacity

10 Best Filters for 30-Gallon Aquarium: Perfect Capacity for Medium-Sized Tanks! (Fall 2022)

The other thing you need to look at is the tank capacity of the filter you are using.

Most filters claim to be able to work with bigger aquariums when they do not. For this reason, you must ensure you get the right size for your home. Filters like NO.17 Submersible Aquarium Internal Filter can still be used with bigger tanks even though they are meant for 30gallon aquariums. They will give you value for your money even when you need to upgrade your aquarium.

Ensure that the filter is powerful enough to get the aquarium clean yet gentle enough that it does not draw in fish. That way, you are sure you are getting a good deal.

Size

The other thing you need to look at is the filter size. While most people prefer smaller filters because they are not bulky, it could work against it. Ensure you get a big enough filter so you have no worries when it comes to the efficiency it comes with. If you have a small tank, then a submersible like AQQA Aquarium Internal Filter will work for you because it is not so bulky that you feel it will damage the tank. As long as it has a high enough flow rate, you can rest assured you are using the right filter size, even for a submersible.

Noise

When it comes to noise, you first need to remember that every filter will have to remember every filter comes with some buzz or hum. All you need to remember is to get a quiet filter, so you do not have to hear it every time. Some filters like the AMOSIJOY Canister Filter are so quiet you barely notice. The hum almost feels like white noise. Such filters are perfect for you if you want to use your filter in the living room or bedroom. They can keep running in the background without interrupting conversation or making it hard for you to sleep.

Installation

When all is said and done, you must ensure you can install your filter without an issue. One of the things many people struggle with is assembling a filter. While most filters are easy to figure out, some come with complex parts and instructions. Since most of them are poorly installed, it can be hard for you to figure out how to reduce the noise the filter emits or how to ensure the suction stay after installation. Getting an easy-to-install filter will ensure this happens.

FAQ

Even though it sounds complicated, it is much simpler than you think. Most people who have used the filter admit that installing it is simple. Here are the steps to flow when installing your filter.

  • Line up all your pieces to ensure there is no missing piece. You might need your manual to countercheck this.
  • Use one hand to grab the holding tank and the other to attach the inflow tube inside the tank. You might need to adjust it so it is in the right place.
  • Attach the tube to the inflow tube.
  • Insert the smaller filter into the tubing in the holding tank.
  • Insert the filter cartridge into the holding tank.
  • Fill the holding tank up to three quarters with cold, clean water.
  • Attach the filter to the back of the aquarium. Ensure it is firmly attached so the filter does not move when working. Some people recommend gluing the filter to the tank or getting more powerful suction cups.

It is recommended that you change your filter anywhere from 2 to 4 weeks. Your filter traps algae and debris, and when left for too long, you end up with a filter that is not functioning. Most filters come with cartridges that can be replaced every couple of months. Despite that, you need to take out your filter and clean out all the debris. That way, no debris will be pumped back into the tank, which will cause the water to be cloudy.

Cleaning out the filter is pretty simple. All you need to do is remove the filter, remove the debris, and rinse it in clean water. Put the filter back into the water and observe how well it filters afterward. It will go a long way to ensure your tank stays clean.

Yes, you must clean your aquarium even when using a filter. Many people think the filter will do all the work for you, but that is not true. Every once in a while, there will be debris in the water that a filter cannot remove. As such, it is recommended that you regularly clean out your aquarium to reduce the buildup of dirt. Doing this ensures that your filter keeps working efficiently, and you do not have to worry about changing the cartridge more often. It also removes any debris your filter might not have removed.

When cleaning out your aquarium, simply take out your fish and put them in a bowl or different tank, uninstall the filter, then clean out the tank and pour in clean water. Once that is done, set up your filter and ensure it runs before you bring back the fish.

Our Verdict

Of all the filters above, we had our top three picks in the categories editors’ choice, the best value, and premium pick. By taking the time to learn about these filters, you can make an informed decision when buying a filter for your home. Our editor’s choice is the AquaClear Fish Tank Filter because of how powerful it is. Most filters on the market have issues when cleaning out debris, but you do not have to worry about that. The AquaClear Fish Tank Filter comes with activated carbon, which makes it easier to ensure the dirt in the water is completely removed. When using this filter, there is no need to go back and clean the aquarium every so often.

Our best value filter was the MarineLand Penguin 200 Power Filter. Even with this price, it still delivers on quality. Most cheap filters can cost you more in terms of the time it takes to clean the water and how often you should wash the filter. The MarineLand Penguin 200 Power Filter is efficient, so there is nothing much to worry about it. It makes the perfect filter when you are on a tight budget.

Our premium pick is the AMOSIJOY Canister Filter. It is a very quiet yet powerful filter. While it might be costly, the value you get from it is worth it. If you are looking for a silent filter, you will not even realize it is working. Go for the AMOSIJOY Canister Filter if you want functionality and convenience. The list above has a detailed guide on the best filters for 30-gallon aquariums for your needs. Peruse through it and pick what works for you and your aquarium.
