Best Aquarium Vacuum

Keeping fish as pets is an almost magical experience. The serenity of the water and the vibrancy of their gorgeous colors and markings can leave you feeling both relaxed and in awe.

The way a fish tank is aquascaped also plays a large part in the experience. Different colored plants and natural-looking ornaments give the tank a realistic appearance that every fish owner strives for. Not to mention, it helps keep your pet fish feeling safe and secure, offering them somewhere to hide out of view if they sense a threat. 

However, keeping your tank looking clean and your fish healthy can be a little bit difficult. Sure, there are filtration systems available that are an invaluable tool for maintaining your tank, but these merely clean the water. 

Every so often you need to give the gravel in your tank a good clean and this is a job that your filter cannot do for you. So what’s the solution? The answer is simple. You need an aquarium vacuum.

These clever gadgets work by sucking up the gravel and churning it around in a column along with the water. This then loosens any debris such as fish waste and dead plant material and removes it before allowing the cleaned gravel to sink back to the bottom of the tank again. 

If you’re thinking of buying an aquarium vacuum but you’re not sure where to begin, don’t worry, we’re here to help. Below, we’ve listed five of the best aquarium vacuums available. We’ve also put together a buying guide that’s packed with information on what to keep in mind before making your final decision.

Best Aquarium Vacuum Buying Guide

Deciding on which aquarium vacuum is best for your aquarium is no easy task, and you certainly can’t ask your fish which one they prefer!

To help make things a little easier, we’ve outlined some key points below to bear in mind when you start shopping around. These will help to guide you in the right direction and find the perfect vacuum for your aquarium the first time around.

Aquarium Size

The first thing to consider when purchasing an aquarium vacuum is the size of your aquarium itself. You need to be able to make sure your chosen vacuum can reach right down to the bottom of your fish tank and make contact with your sand or gravel.

Luckily, researching this is pretty straightforward. Take a look at the hose length the vacuum you’re thinking of purchasing has and measure this against your aquarium. Bear in mind that you’ll need to leave an allowance for one end of the hose to reach your substrate, and the other end to reach the receptacle you’re collecting the water in. 

Type of Substrate

It’s a good idea to check that your potential new aquarium vacuum is suitable for the substrate in your fish tank too. The two most commonly used substrates are gravel and sand, however, gravel is much larger than sand and is, therefore, harder to clean.

If you do have sand lining the bottom of your aquarium, look for a vacuum that comes with a special sand attachment. This will feature a very fine mesh filter that, almost magically, sucks up debris whilst ensuring no sand is lost in the process.

Attachments

There are loads of different attachments to look out for when you’re purchasing an aquarium vacuum and each will be specially designed to carry out a specific cleaning task. To get the best value for money, it’s a good idea to look for an aquarium vacuum that comes with a good variety of attachments. 

Gravel or sand filters are an essential attachment as they’ll clean your gravel without sucking any into your wastewater. Another great attachment to look for is a duckbill suction inlet. This is ideal for cleaning the interior walls of your aquarium and sucking away any algae build-up.

Some aquarium vacuums come with a faucet attachment too. This will allow you to refill your aquarium after a water change directly from your faucet and takes away the need to heave heavy buckets of water back and forth. 

Although not strictly an attachment, a non-kinking hose is a good thing to look out for as well. This will allow you to get into the harder to reach areas of your aquarium and carry out a thorough clean without the water pressure or suction power being affected. 

Durability

Finally, you need to make sure that your chosen aquarium vacuum is going to last you a long time. The best way of ensuring this is to take a look at the materials used in its construction. Plastic attachments are by far the most durable and are highly unlikely to break or corrode under water pressure.

A host made from PVC is the best choice to go for as well. This won’t easily suffer from cracks and will be incredibly hard to accidentally puncture.  

Make sure that the plastic used in the construction of your aquarium vacuum and its accessories is BPA-free though. This means that no harmful chemicals will leach out into your aquarium’s water whilst you're cleaning and, in turn, keeps your fish and live plants completely safe. 

Frequently Asked Questions

How often should you clean your aquarium?

This can vary depending on the breed of fish you have, however, the general recommendation is to clean your aquarium every one-two weeks by carrying out a partial water change. You should also remove any debris from your aquarium’s substrate using an aquarium vacuum.

What does an aquarium vacuum do?

An aquarium vacuum has two functions. The first of these is to clean your aquarium’s gravel or sand without losing any in the process. It manages this by sucking it up into a specially designed chamber and spinning it clean to remove any debris before releasing it back into the tank. Secondly, it can be used to siphon water out of your aquarium and make water changes quick and easy. 

Should you leave your fish in the tank while cleaning?

You may worry that you could hurt your fish while you are cleaning. But, it is actually better for the fish to stay in the tank while you clean. In most cases, you won’t need to remove all of the water in the aquarium. Therefore, your fish will still be able to swim around. It will be more stressful for your fish to be taken out of the tank than it would be to be gently cleaned around with an aquarium vacuum.
