The quietest aquarium filter will keep your aquarium water healthy for your pet fish quietly without causing unwanted noises.

According to a 2011 research published on the University of Vienna website, pet fish such as goldfish are heavily masked under artificial conditions and cannot fully exploit their excellent hearing capabilities in noisy environments. Aerators and other sound sources such as aqua filters not only affect fish physiology but also affects its growth.

Another research article published in the Journal of Experimental Biology suggests that goldfishes are highly susceptible to hearing loss and noise-induced stress.

From the two references above, it’s evident that exposing aquarium fish to noises not only interferes with our quiet living but also has detrimental effects on the fish as well.

Buying a quiet aquarium filter will not only improve the quality of your life but will also improve the health and quality of life for the fish as well.  Below is a guide on some of the quietest aquarium filters.

 Quietest Aquarium Filter On the Market?

The best quietest aquarium filter is MarineLand Penguin 350 BIO-Wheel Power Filter. It comes with a rotating patented bio-wheel technology that gives an excellent wet or dry biological filtration.

The filter provides chemical, mechanical, and biological filtration to give a clean aquatic environment.

The filter is compatible and can be used with the MarineLand Rite-Size filter.

The product is available in 5 different sizes that are; 75 GPH, 00 GPH, 150 GPH, 200GPH, and 350 GPH, and it is ideal for use in all life stages.

The MarineLand penguin Rite size filter cartridges come ready for use with each filter ready for removing waste, odors, and fixes discoloration.

Each cartridge has a faster-acting Black Diamond Premium activated carbon to ensure efficiency.

Bio-filtration is enabled by the revolutionary and patented BIO-wheel that has been proven to remove ammonia and nitrite.

Bio wheel filters have adjustable mid-level intake strainers and noise reducing two-piece vented covers.

The  filter work effectively in 3 stage aquarium filtration without straining air pumps, valves, and air stones or tubing.

The filter requires no virtual set-up making it ideal for anyone to install with the aid of the manual. Ensure you prime the filter with the aquarium water before plugging it in.

After setting-up, you can now adjust water flow with the mid-level strainer.

Filter maintenance is easy; you just simply remove and replace the filter cartridge after around a month and clean as per the requirements.

Make sure you have maintained enough water levels in the tank so that the filters run quietly.

While MarineLand Penguin 350 above may sound like the real deal, there are other options you can choose from. Below is a detailed guide of some of the other quietest aquarium filter (s) you can find on the market today.

Types of Quiet Aquarium Filters

Canister Filter

These external aquarium filters are often the quietest and take up no space within the tank.

In most situations, a canister filter is placed beside the aquarium, although it may also be placed underneath the tank (if there’s enough space for it). Each canister filter has a set of hoses to clean the tank’s water.

These hoses will remove aquarium water and transport it to the filtration itself. When water enters the apparatus, it will be forced through a succession of filter media under pressure. It is important to note that a canister filter may perform mechanical, biological, and chemical filtering simultaneously, provided the right medium is used.

Once the device has effectively filtered the water, the freshwater is returned to the aquarium via a second hose. The soil is contained in a specific container within the container.

Hang On Back (HOB) Filters

For a good reason, the Hang on Back filter is the most preferred choice among aquarists. It is simple to install and maintain and has almost no disadvantages.

Hang-on-back aquarium filters might be among the quietest filters available. Because they are water-driven, HOB filter motors are among the quietest while operating.

However, similar to any other filtration system, this one must be cleaned and maintained regularly. Even with the smallest tasks, many things can go wrong; therefore, it is essential to perform maintenance correctly.

Cleaning the tank filter is a particularly contentious task that many inexperienced aquarium owners tend to exacerbate.

Unlike canister filters, which may last four months without being cleaned, HOB filters must be cleaned more frequently. A HOB filter should be cleaned every two to three weeks or more frequently if necessary.

Undergravel Filters

As their name implies, these filters are put beneath an aquarium’s gravel layer. These filters circulate water through gravel to facilitate biological filtration. Once helpful bacteria populate the gravel, they begin to decompose waste effectively. To work, undergravel filters require either a powerhead or an air pump to function.

Primarily, undergravel filters are biological filters. Many types, however, have a replacement cartridge put at the end of the rigid tube to give further chemical or mechanical filtering. They are available for small and big aquariums; however, they work best in aquariums with a low fish load.

Air Driven/ Sponge Filter

This basic type of filter needs at least three parts: a sponge filter (which resides within the tank), an air pump, and air tubing to link the two. The air pump forces air through the tube and into the sponge filter’s hollow chamber.

The rising air bubbles suck water through the walls of the sponge, so mechanically removing detritus from the water and providing a habitat for good microorganisms.

Pros: They are inexpensive, simple to clean, and difficult to damage because it contains few mechanical parts. It delivers good water flow and surface agitation without suckling fish fry, shrimp, or other organisms.

Additionally, during blackouts, the good bacteria on the sponge remain in the oxygenated tank water (giving it a greater chance of survival), and you may even purchase rechargeable air pumps as a precaution.

Cons: The sponge filter consumes physical area in the fish tank; thus, it may be necessary to conceal it under a rock or other aquarium decorations. Additionally, there is no option for you to add chemical filtration if necessary. I wouldn’t say I like the bubbling sound of a sponge filter, but this is readily addressed with an air stone.

What to Consider When Looking for the Quietest Fish Tank Filters

There are several factors to consider before buying an aquarium filter. Below are some of the most important factors to put into consideration to ensure you get an aquarium filter that meets your specific requirement.

Aquarium size and Type of filter

you need to buy a quiet aquarium filter that will support the size of your aquarium. Don’t buy a filter that is too small for your tank since the Water will still look dirty.

There are many filters available in the market, so make sure you choose that which suits your needs.

Each filter will have its pros and cons; for instance, canister filters are quiet and require less maintenance, but they are costly while the power filters are cheap and big but will produce some annoying sounds.

Check also the other accessories and how to maintain the unit.

Filtering process and Water flow control

There are different filtering processes, and each has a different task. Chemical filtration is suitable for water discoloration and removal of bad odors.

Mechanical filtration removes debris from the aquarium while the biological one keeps the fish and tank environment clean.

If you have all the above issues, go for a filter that has multiple trays.

Water flow control Self -priming

It allows you to control the speed that the water is flowing from the filter. It enables you to deal with different aquariums in certain gallon range.

Different kinds of fish require different rates of water flow; that’s why you have to be keen when buying the filter.
