Best Aquarium Vacuum Cleaner

Many people involved in the fishkeeping industry aren’t aware of the potentially harmful effects that having dirty gravel or substrate in their tank can cause. Since the substrate is always in the water, most people automatically assume that it will always remain clean. But like any other object in your fish tank, the aquarium substrate has the ability to collect harmful dirt and grime, sometimes even more so than other items in the aquarium.

Given that substrate is located on the bottom of your fish tank, it can be the dirtiest element in your aquarium. Fish waste, debris, and other chemicals end up falling to the bottom of the tank at some point and they accumulate in-between the air pockets of the substrate. Because of the potentially harmful effects that having dirty substrate can cause, you should make sure that the substrate in your aquarium is always clean and healthy.

More specifically, you can clean your substrate by using an aquarium vacuum. They’re responsible for sucking up the substrate pieces in small groups at a time, ultimately removing any unwanted substances from the gravel, sand, or rocks. But it can be difficult to find the right aquarium vacuum on the market for your specific needs. Consequently, here is a complete guide that I’ve compiled together for you to reference to during your vacuum buying process. Not only that, but I’ve also included five of the best aquarium vacuums on the market.

Different Types of Aquarium Vacuums

Standard vacuums

Standard aquarium vacuums are able to function by a tube that’s inserted into your aquarium tank. Some standard tubes have a slanted end while others have a flat end on the tube. The tube that’s inserted into the aquarium water is them able to suction out all of the dirt and debris from the substrate after it’s inserted into the substrate material.

After the dirt is suctioned from the substrate, it then travels through the tube and lands into the bucket that’s located on the outside of the tank, usually on the ground. Standard vacuums come in a variety of different shapes and sizes, so you have the ability to choose the ones that best benefit your specific needs.

Mini vacuums

Mini vacuums operate in a similar fashion to standard vacuums, in that they effectively remove the dirt and debris from your aquarium substrate using a suction motion. They differ from other vacuums because they’re smaller and more portable than other vacuum devices. Because of that, they’re recommended for aquariums that are smaller in size, since the gravel and substrate is likely smaller particles.

They’re also recommended if you have sand as a substrate, since their suctioning function is weaker than other devices and it won’t suction the sand into the tubing.

Self-priming vacuums

Self-priming vacuums have the ability to use suctioning to remove dirt and debris because of your pumping the tube. By pumping the tube, you’re essentially priming it in order for the device to have enough suction motion to effectively remove dirt and debris.

Water-driven vacuums

Water-driven vacuums have the ability to function by water flowing through its tubing. When the water flows through the tube and out the other side, it’s able to create a suction that can then allow the vacuum to operate properly and remove the unwanted dirt and debris from the substrate.

Some water-driven vacuums are able to not only remove water from the tank with the dirt and debris, but they may also be able to refill the tank as well. This prevents you from having to refill the water in the tank that was lost during the cleaning process.

Filter-driven vacuums

Some aquarium vacuums also have the ability to operate by using the filter’s energy. More specifically, filter-driven vacuums are able to effectively attach to the inlet tube of the filter, which then is used to pull water through the filter as well as the dirt and debris from the substrate that the other end of the tube is placed into (1).

Things to Consider Before Purchasing

Aquarium size

You should consider what size your aquarium is, since you’ll want to find an aquarium vacuum that’s able to clean your substrate in an adequate amount of time. You don’t want to be spending hours cleaning just the substrate of your fish tank. Not only that, but you may find it beneficial to consider what size the substrate particles of your tank are. You don’t want the vacuum sucking up the small pieces of the substrate if you have a vacuum that sucks too hard on the substrate that’s too small for it.

Organisms in your aquarium

It’s important for you to consider what type of organisms you have living in your aquarium, since this will ultimately determine how dirty your substrate is as well as which organisms you’re recommended to remove from the tank before cleaning the gravel. You generally should remove all of the fish from the tank before you clean the substrate, since you don’t want the device to suck up any of the fish.

Type of aquarium vacuum

Lastly, you should consider what type of vacuum would work best for your needs. There is a wide variety of different types of vacuums on the market, so you should review the different types and then choose the one that functions in the best way for your specific preferences (2).

Frequently Asked Questions

How often should I vacuum my fish tank?

It depends on the type of organisms that you have in your tank, since the rates that they produce waste vary. But you should generally use an aquarium vacuum for your substrate at least once a month. Many people think that simply changing the water of their tank is enough to provide adequate cleaning for their tank, but you should be vacuuming the substrate, since it’s likely the dirtiest element in your tank.

How do aquarium vacuums function?

There are several different types of vacuums for your fish tank that can function in various ways. Some vacuum products are water-driven and only require water in order to operate, while other vacuums require that you suck the water through the tubing manually. You can find different types of vacuums with various functions available on the market.

Why do I need to vacuum my aquarium?

You’re required to vacuum the substrate in your aquarium because the substrate likely contains the most dirt and debris that can accumulate and lead to problems if it’s not cleaned. Not only that, but you should vacuum the substrate in your aquarium because it will lengthen the amount of time that you can go without changing the water in the tank (3).
