Types of Aquarium Filters: Which Option is Quietest?
External filters are the quietest option, with internal and hang on back (HOB) filters being close runners-up. All three of these types of filters are very effective at filtering your aquarium water and keeping your fish healthy.
External (Canister) Filters
External filters are the quietest option available and are perfect for large aquariums. They sit outside of the aquarium and use a pump to push water through the filter media, which cleans and oxygenates the water. Because they’re external, they don’t take up any space inside the aquarium and don’t disturb the fish.
External filters also have the largest filter media capacity, so they can hold a lot of waste and debris.
The water is pumped from the aquarium into the filter, where it passes through the filter media and is then pumped back into the aquarium. These filters are best for extremely large aquariums because they don’t have a water reservoir.
Instead of using a pump to push the water through the filter media, external filters use gravity. The filter media is elevated above the bottom of the tank and water trickles down through it on its way back into the aquarium.
Internal filters are a great option for small and medium-sized aquariums. They sit inside the tank and use a pump to push water through the filter media, which cleans and oxygenates the water.
Internal filters are very compact and take up very little space inside the aquarium. They also have a smaller filter media capacity than external filters, so they can’t hold as much waste and debris. Internal filters.
Sponge filters are a type of internal filter that are extremely quiet and doesn’t require any maintenance. They’re made of a sponge that traps debris and bacteria, which breaks down ammonia and nitrates.
Sponge filters work best in shrimp tanks and small aquariums with low fish populations. They’re powered by an air pump, which draws water through the sponge and back into the aquarium.
HOB (Hang On the Back) Filters
Hang on back filters are mounted on the back of the aquarium. They’re an inexpensive option for small to medium-sized aquariums and usually do a good job at keeping fish healthy. Like internal filters, HOB filters use water pressure to push water through the filter media, which cleans and oxygenates the water.
HOB filters are one of the quietest aquarium filters available and don’t take up a lot of space inside the tank.
Undergravel filters are the quietest internal filter. They attach to the bottom of the aquarium and use gravel or other substrate to create an area for beneficial bacteria to grow, which breaks down waste in the water.
Undergravel filters are one of the oldest types of aquarium filtration systems around and have been around since some aquarists were still using clamshell aquariums. They’re very inexpensive, but they need to be cleaned regularly and don’t work for tanks with high fish populations or tanks that are heavily stocked.
This filter works by pushing water through the substrate of the aquarium, which is where bacteria breaks down ammonia and nitrates. The gravel itself has no mechanical filtration properties and may actually trap some debris, which will need to be cleaned out regularly.
What to Consider When Choosing the Quietest Aquarium Filters
The quietest aquarium filter can be any type of aquarium filter, from external filter to sponge, and hang on back filters that might add value to the fish tank. Flow rate and filtration stages are important when choosing the best aquarium filter.
There are several other details that need to be explored. The following section highlights the key considerations.
The size of the aquarium is the first consideration that should be made, because different filters are suited for different sized tanks. The easiest way to determine what filter would best suit your tank is by finding the gallon capacity of your aquarium and then matching it with a filter that can accommodate it.
Tip: You should be aware that the size of filtration media is a big consideration for determining its capacity.
The flow rate is how much water the filter can move per hour. It measures how much water flows through the pump and filtration system in a given period of time, usually measured in gallons per hour (GPH).
The higher the flow rate, the more water the filter can move and the faster it can clean the tank. This is an important consideration if you have a high fish population or a tank that’s heavily stocked.
Always go for the highest flow rate that best fits your budget. The flow rates should be listed on the filters you look at so you can compare them directly to each other. You’ll want
Filters typically carry out several filtration stages, which are marked by different types of media.
- Mechanical filtration is achieved by using clean or biological filter media to capture larger debris and prevent it from clogging the other filters in the system.
- Biological filtration is achieved through either sponges, ceramic rings, or bio-wheels, which contain beneficial bacteria that breaks down fish waste and other debris.
- Chemical filtration is often achieved through activated charcoal, which traps impurities in the water. This media must be replaced regularly because it quickly becomes saturated with debris.
The number of filtration stages a filter has will affect how quiet it is. More stages usually mean a slower flow rate, which makes the filter quieter.
Tip: If you have a high fish population, you’ll need a filter that has more than one stage for mechanical filtration.
Ease of Use
Some filters are much easier to use than others. For example, filters that hang on the back of the tank are very easy to install and don’t require any tools. On the other hand, undergravel filters require a fair amount of work to set up and can be difficult to clean. The best filter is the one that’s easiest for you to maintain.
Fluval 407 External and Canister Filter is the quietest external filter, by far. It’s also easy to clean and doesn’t produce a lot of noise. The two internal filters mentioned are also great options that provide very low noise levels. However, Fluval 407 still wins out as one of the quietest aquarium filters because it provides crystal clean water while also being easy to clean and having a very quiet motor.
How We Choose the Quietest Aquarium Filters
We’ve done a lot of research to find the quietest aquarium filter out there. I know what you’re thinking: “That’s impossible!” But keep reading, and I’ll explain how we did it. First off, to find the quietest aquarium filter, we bought and reviewed each of them.
We then narrowed down our options by looking at user reviews and ratings. After that, we looked for filters with high energy efficiency and low sound levels under normal use. People who own aquariums know how important it is to have a filter. Without one, your fish would die of ammonia poisoning in no time at all. That’s why we included only the best filters around.
How to Make a Noisy Fish Tank Filter Quieter
Filter noise is an important factor when choosing a filter for your tank. If you can’t stand the sound of your aquarium filter, there are some things you can do to reduce the noise without sacrificing filtration.
One is to place a piece of sponge over the intake pipe. This will help to muffle the sound of the water flowing through the filter. Another thing you can do is to try and orient the filter so that it’s pointing downwards instead of upwards. This will help to slow down the flow of water and make it less noisy. Finally, you can also try adding some extra plants or decorations in the tank, which will help to dampen the sound of the water moving around.
Another way to make it quieter is to ensure that any exposed parts around the water pump are properly sealed so no water can escape and create noise.
Fish tanks are not difficult to maintain, whether the aquarium size or the type of fish you have, is best to keep it running with one of the quietest aquarium filters. Those who plan on maintaining a fish tank have some questions about the quietest fish tank filter.
Q: How loud should an aquarium filter be?
An aquarium filter is quiet if it operates at around 26 decibels or lower. Every filter is different so some can be more silent than others while some may produce more noise, making the levels hard to pinpoint.
One of the quietest aquarium filters is Fluval 407 External and Canister Filter, rated at just 26 dB of noise. This external filter circulates 405 gallons of water per hour and is perfect for tanks up to 150 gallons.
Q: Is a loud filter bad for fish?
A loud aquarium filter is not bad for your fish as long as the noise level does not exceed 40 dB. Anything that is louder than 40 dB can start to cause some stress to your fish, but it won’t kill them.
Q: Are all fish tank filters noisy?
No, not all aquarium filters are noisy. In fact, many of them are very quiet and won’t disturb you or your fish. The filters we recommend in this article are all known for being the quietest aquarium filter on the market while still providing excellent filtration.
Q: Is it ok to turn off the aquarium filter at night?
It is not recommended to turn off your aquarium filter at night. Not only will it disrupt the water quality, but it can also be dangerous for your fish. Turning off your aquarium filter can cause the water to become cloudy and bacteria levels to spike. It’s best to keep your filter running 24/7 unless you have a very low.
If the current filter you have is making a lot of noise and is not letting you sleep, replace it with Fluval 407 External filter, one of the quietest aquarium filters. With this silent filter, you will have a good sleep without filter noise disturbing you.
