7 Best Aquarium Water Changers 2022

Building your aquarium is one of the most fun things to do, from deciding what plants and substrate to purchase to determining which creatures would thrive in your tank. However, even though building your perfect aquarium can be a wonderful hobby, it requires a lot of maintenance, particularly when it comes to changing water.

Changing the water in an aquarium must be done every two weeks. Even though it can be challenging, aquarium water changers provide you with an easy solution. This guide will walk you through a list of the top seven best aquarium water changers. Next, we’ll walk you through a buying guide and an explanation explaining why you need a water changer.

Let’s take a closer look!

What is an Aquarium Water Changer?

An aquarium water changer is a practical device designed to fill and empty an aquarium. It is similar to a gravel vacuum that works to clean out waste from the substrate in the aquarium. However, unlike a gravel vacuum, the aquarium water change can be attached to a faucet. Most aquarium water changers come with a faucet adaptor, a gravel tube, and a water flow sink attachment.

The aquarium water changer pulls water from the tank and empties it into a sink or bucket. It is convenient because using the water changer means that you don’t need to siphon water.

To use an aquarium water changer, you must do the following:

  1. First, you need to attach the water flow assembly to a faucet. You will need to use the faucet adaptor to secure the water flow attachment.
  2. Next, you need to put the gravel tube in the aquarium water. Please ensure that the tube is fully submerged. 
  3. The water flow assembly attachment has two valves on it. Close the gravel tube valve, making sure you open the water flow assembly valve.
  4. Switch on the faucet. The gravel tube will start to vacuum the aquarium.
  5. Once you are satisfied with the amount of cleaning that has taken place, open the gravel tube valve and close the water flow assembly valve.

The aquarium water change siphons water while cleaning the tank simultaneously!

Buyer’s Guide: Best Aquarium Water Changer

There’s a list of factors to consider when buying an aquarium water changer. Here is our quick buyer’s guide to help you select the best water changer to suit your needs.

1.    The size of your tank.

It’s essential to consider the size of your tank before you buy an aquarium water changer. For instance, if you have a small tank that fits only three medium-sized fish, you don’t want to purchase a water changer with a 25-foot long hose! The long hose might siphon the water too quickly and accidentally suck a fish or plant out. Therefore, you must assess the aquarium size before buying a water changer.

2.    The aquatic life in your tank.

When buying a water changer, you must also remember to consider the creatures and plants that live in your aquarium. If you purchase an aquarium water changer with a hose with a large nozzle, you want to ensure that it won’t kill a fish by siphoning it with the water during a water change. Keep the aquatic life in mind!

3.    The number of features offered.

Make sure that you carefully read through the number of features that a water changer offers. For instance, if you can find a product that fits a wide variety of faucets, it is worth buying.

Why Do You Need an Aquarium Water Changer?

It would be best to have an aquarium water changer to help your fish and plants remain healthy.

Changing the water in your aquarium is more important than you might think it is. While the water might look clean and clear when you peek through the glass, you will come to realize that it isn’t if you start to move the substrate around.

When you feed your fish or other aquatic creatures, they don’t always eat every food particle dropped in. Instead, their food sinks to the bottom of the tank. Fish excrete urine and feces after eating. The bodily waste that they expel lowers the water quality. The water changer will also help you get rid of built-up phosphate and nitrate waste.

The combination of bodily waste, minerals, and other bacteria that accumulate over time all contribute to the water’s chemistry, which, in turn, affects the quality of life of the fish and plants in your aquarium. This is where the aquarium water changers come into the picture. Therefore, it would help you have an aquarium water changer to filter out the waste and debris from the fish tank while adding fresh water to help your fish and plants thrive.

What Problem Comes With ALL Water Changers?

A common problem with all water changers is the water flow assembly attachment. This attachment fitting comes in only one size and can cause problems when people have faucets that cannot fit the water flow attachment.

However, while it is a frustrating problem, we’re here to tell you that there is a simple solution. All you need to do is go to your local hardware store and purchase a faucet adaptor. Once you do that, you need not worry about fitting the water changer attachment onto the faucet you have. 


How to Dry Out Aquarium Water Changer Hose?

One of the easiest ways to dry out the hose is to hang it from a height and let the water drip dry. If you have a shower rod in your bathroom or a hook in a storage closet, you can hang the hose up with the two open ends facing down and let it dry. When hanging the hose in an area like a storage closet, we’d recommend placing a bucket underneath to catch any lingering water.

How Often to Change Aquarium Water?

You must change your aquarium water every one to two weeks. If you cannot change it every week, you must make sure to change it every two weeks.


This guide took you through a list of seven of the best aquarium water changers. When you go through putting an aquarium together, you must remember how important it is to maintain the health and well-being of your fish and aquatic plants. Changing the water in an aquarium is one such way to do so! Aquarium water changers make the process of changing water much less time-consuming and difficult. Once you’ve purchased this device, we can assure you that you will get this task done in no time at all!
