What is an aquarium water changer?

If your fish are to be healthy and thriving, the water in their tank must be kept clean and free of harmful toxins such as ammonia, nitrites, and nitrates. These three substances appear as part of the natural nitrogen cycle in your aquarium when fish waste, uneaten food and decomposing plant matter pollute the water.

In the wild, these nitrogen compounds are swept away by currents or diluted by rainwater. However, this is not the case in the closed environment of your home aquarium.

An efficient aquarium filter system helps keep toxin levels low. However, you will also need to perform a partial water change and vacuum the substrate every week to prevent these substances from building up and potentially poisoning your fish.

An aquarium water changer is a simple siphon-based device that allows you to suck water out of your aquarium along with fish debris, uneaten food, and corrosive organic matter, and dump any dirt you don't want in your aquarium straight into an aquarium sink or buckets, depending on the type of system you choose.

Most water changers have a long hose that attaches directly to the tap. The device first removes dirty water from the tank and then replaces it with clean tap water. Aquarium water changers are designed to prevent you from carrying heavy buckets of water to and from the aquarium and to prevent spills and spills.

What to look for when buying an aquarium water changer

Aquarium water changers work in much the same way, although there are a variety of styles to choose from. You should consider the following when purchasing an aquarium water changer:


The cost of aquarium water changers varies a lot, so you can almost certainly find one that suits your budget.

As a rule, the more expensive the product, the better the quality. Cheaper aquarium water changers tend to be less durable and more prone to leakage or suction than their more expensive counterparts.

So we encourage you to read other buyers' reviews to check the quality and performance of the product before parting with your money.


The maxim “buy cheap, buy twice” also applies to aquarium water changers. You want to buy the best quality product that you can afford. Badly manufactured devices are not only less efficient. They tend to fall apart quickly, which means you will need to buy a replacement.

Maintaining tanks can be hard work and costs plastic and rubber components. So always check that the water changer you are about to buy is made of durable, high quality materials.

Range of functions

Some water changers for aquariums offer additional functions such as multifunctionality, extra long hoses or specially developed filters. Take the time to read through all of the features that each product has to offer before parting with your hard-earned cash.

A particularly important function is that the device fits on a number of taps. For a water changer to work effectively, it must fit properly into the tap without leaking. A fully adjustable faucet faucet can save you a world of pain in the long run.

user friendliness

The whole point of buying an aquarium water changer is that if you have to partially change water and clean your aquarium substrate, you save time and hassle.

Check to see if the product you are trying to buy is a plug-in-and-go device or if it requires manual setup, which can be problematic.

Size and hose length

The size of your tank has a great influence on the aquarium water changer you have purchased.

Typically, if you have a very deep tank you will need a very powerful water changer that has enough suction to pull the water out of the tank at a relatively fast rate. If your aquarium is some distance from the nearest sink that you can use for water changes, you need to choose a product with a hose long enough to comfortably stretch from the tank to the sink.

Final thoughts

Keeping the water in your aquarium clean and performing partial water changes every week is critical to the health and wellbeing of your livestock. Changing water and cleaning tanks can be time-consuming, messy chores at best, and anything that makes the job faster and less stressful is worth adding to your fish farming kit. An aquarium water changer is an ideal device for this job.

All of the aquarium water changers that we have discussed for you in this guide are bestsellers and do a good job. Choose a product that fits your budget, has all of the features you want, and is easy to use. You can look forward to faster and easier tank maintenance.
