Silent fish tank filter buying guide

Make Sure You Choose A Suitable Filtration Process

As soon as you buy a new filter, test if it is even good for your system. You can choose from three distinct filtration systems whichever suits you best. However, they all work in different ways. For example, the mechanical one can remove rubbish from the aquarium.

These systems have pre-installed devices that are programmed to remove the waste product of fishes. You can opt for these filtration systems if you have large fishes as they defecate too often and if not cleaned time to time it may pollute the aquarium. 

Besides mechanical systems, there are also chemical filtration systems available. These systems keep an eye on the color of water in case it is discoloring and maintain a nice odor in the aquarium.

The last type of system; the biological filtration system is best for you if your fishes make a mess real quick and defecate too often. 

These systems clean up the mess from time to time and maintain a clean environment in the aquarium. If you are thinking that you need all of the three systems because my fishes have all these problems, opt for multiple trays filter.

These trays are multi-tasking that are suitable for different filter mediums and work well for all types of waste and mess in the fish tank.

Take Your Fish Tank/Aquarium Size Into Consideration 

The type and size of these systems depend upon the size of your tank. These systems are quite fascinating but you need to choose the suitable size and shape of them. Buy the filter that fits best with the capacity and size of your fish tank.

For instance, it would be foolish to buy a 50-gallon capacity filter for a tank that has a capacity of only 10-gallon water. Not only will it be a waste of money but it would be useless. 

Likewise, don’t choose a too small system for a large tank because it would not be able to work well and leave plenty of mess. This is why it is important to complement the filter size and the size of the fish tank.

Evaluate All The Types Of Systems And Their Features

We have mentioned different types of aquarium filters available in the article. It is for you to decide which machine is best suited to your needs. 

Every one of the five systems is unique in its own way and has distinct pros and cons. Evaluate these points before spending money on them.

For example, power filters are quieter and have adjustable sizes, while canister filters require minimum maintenance and are quieter than the power filters.

However, they are more expensive besides having cheaper alternatives. Overhead filters, on the other hand, require more space and are not so quiet compared to other options.

While choosing filters, consider maintenance duration and costs of either of them. 

Noise Production

Filters utilize motors to drive the system so it is pretty obvious that they produce some noise while working. Now you might think that a quiet fish tank filter may not produce sound but it simply means that they have an insulation system for the noise produced. 

In most filters, there is a protective cover that lessens that noise and vibration to a bearable degree.

Besides these covers, there are intake strainers that dampen the sound produced by the vibration of motors. The more the noise is dampened, the happier the fish and you are. 

Look For A Self-Priming Feature In Your Machine

You should pay most attention to this factor while choosing a filter. Your system should have a self-priming property in it.

This feature allows to maintain the water flow through the filters by keeping the path clear.  This is helpful if you have a power breakdown issue or if you have inconsistent voltage in your area.

The air is sucked out by switches that prevent obstruction whenever you face a power breakdown. And the fishes won’t even feel the drop when the power is back. 

Judge The Water Flow Control Mechanism

You need to give minimum control of the water to the system. You must be able to control the speed and amount of water yourself as necessary.

It helps when you have many aquariums with different water ranges. Different fish live in different water ranges and at different speeds.

Fishes such as goldfishes and guppies have distinct living environments and water flow. If you can’t control that one of them would be suffering. You need to have a switch or any other controller for that purpose. 

However, some filters don’t work well on less speed. Choose the filters which maintain quality even when speed is reduced. 

Aquarium Filter Types and Tank Sizes

Air Driven Filter

Even though they are small, these types of filters can still be very sturdy and well-constructed. The air pump of the aquarium sucks in air and supplies it to the filter. 

The basis of this is that these are supposed to function the air pumped into the aquarium. With the help of these filters, you can keep your marine life completely healthy, unharmed and at peace.

You will require a panel normally in the corner of the water tank to place this filter. This filter is not very noisy.

The design concept has been strategically oriented to be compact in order for them to be perfect for workspaces, hospitals, and homes! 

Power/Hang back Filter

The hang back filter is definitely the most common filter in most aquariums. This filter is suitable for water tanks of capacity up to 10 -55 gallons of water.

They are not only long-lasting but also have an easy installation system. Most of the people prefer it because it is suitable for all three filtration systems. 

They create a stunning effect of a waterfall due to them hanging on the side of the wall of your aquarium. Every 4 days, the water should be replaced to avoid the sounds of splashing. These are pretty low noise but need some maintenance.

We would not recommend this type of filter unless you’re willing to stay on top of regular maintenance.

Canister Aquarium Filter

The basic advantage the canister filter provides is that it allows the tank water to go through different filtration mediums. Therefore, the goal is to cleanse the water at the end.

These filters are very quiet due to them being placed in a strategically oriented cartridge on the outer side of the aquarium. 

You won’t be bothered by splashing sounds due to the process of returning the water via the tube, thus making it completely soundproof.

You will also experience no humming or vibration noises during use. Also, all of these filters come in an ergonomic sleek design, ensuring compactness to maximize ease of use.

Overhead Filter

These are very common types of filters. The rear part of the filter is attached to the top of the water tank. This causes the water to splash in the tank. Due to this, it is not completely noiseless. They are quite reasonable when it comes to noise production.    

Undergravel Filter

In the event that you don’t need your filter to be obviously visible, this is the perfect alternative. These are set at the lower part of the tank. 

They move the water through the rock to make conditions for natural filtration to happen, where gainful microscopic organisms separate the losses in the fish tank. 

There are huge loads of conceivable aquarium arrangements, and you should consider yours when picking a channel. 

At the point when you enter the page, you’ll first see a speedy route table there. Locate your ideal aquarium size in it and snap on its separate connection to create a stable and robust system.
