The TERA Pump Geniune Aquarium Water Changer is a much cheaper alternative to the rather pricey Python system. That said, it’s still a reliable and efficient system that does the job effectively.

This aquarium water changer is designed for use with fish tanks of 10 gallons or greater, as the suction tube is large. The hands-free design features a discharge hose clip that attaches to your container, preventing the hose from falling off.

There’s also a suction cup that keeps the siphon tube firmly in place, allowing you to operate the pump with one hand. The pump nozzle has a filter that prevents gravel and large pieces of debris from blocking the hose.

The water changer is pretty powerful, shifting around 1.5 gallons per minute.

What we like:

Aqueon has an enviable reputation for manufacturing high-quality equipment for use in fish tanks, and their Aqueon Aquarium Water Changer is another popular addition to their range of products.

The system’s goal is to eliminate the need for lugging heavy buckets of water from the tank to the kitchen sink and ruling out the risk of mess and spills. To operate the system, fix the water flow assembly to the faucet using the multi-connection faucet adapter supplied, and turn on the faucet.

The system’s vacuum element produces the perfect amount of flow to agitate the gravel so that loose waste and debris are removed directly into your sink. The gravel tube features an easy-grip molded handle and an integral on/off valve that gives you complete control over the water flow, and you can adjust the valve on the sink attachment, too, to prevent splashing and mess.

If you do have any problems with the device, the Upettools team provides 24/7 customer support, and a lifetime warranty is provided for your peace of mind. However, the main issue that we can see with this system is that your tank needs to have a spare power outlet where you can plug in the device. The chances are that you’ll unplug your lights while you are cleaning the tank anyway, so you could use the free plug socket for your aquarium water changer.

What we like:

  • Powerful suction saves you time

  • Suitable for saltwater and freshwater tanks

Room for improvement:

What is an aquarium water changer?

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

In the wild, those nitrogen compounds are swept away by the current or diluted by rainwater. However, that doesn’t happen in the enclosed environment of your home aquarium.

An efficient aquarium filtration system will help to keep the toxin levels down. However, you also need to carry out partial water changes and vacuum the substrate every week to prevent levels of those substances from accumulating, potentially poisoning your fish.

An aquarium water changer is a simple siphon-based device that’s used to suction water from your tank, together with fish waste, uneaten food, and decomposing organic matter, depositing all the muck that you don’t want in your fish tank directly into a sink or bucket, depending on the style of system that you choose.

Most water changers have a long hose that attaches directly to the faucet. First, the device removes dirty water from the tank and then replaces it with clean tap water. Aquarium water changers are designed to save you from having to carry heavy buckets of water to and from the aquarium and rule out spills and mess.

What to look for when buying an aquarium water changer

Aquarium water changers work in pretty much the same way, although there are a variety of styles to choose from. Here’s what to look for when buying and aquarium water changer:

Cost

There’s a wide variance in the cost of aquarium water changers, so you can almost certainly find one that suits your budget.

As a general rule, the more expensive the product, the better the quality will be. Cheaper aquarium water changers tend to be less durable and are more prone to leaking or offering poor suction than their more expensive counterparts.

So, we recommend that you read other buyer’s reviews to check the product’s quality and performance before parting with your cash.

Quality

Similarly, the maxim “buy cheap, buy twice” is certainly applicable when it comes to aquarium water changers. You want to buy a product of the best quality you can afford. Poorly made devices are not only less efficient; they tend to fall apart quickly, meaning that you’ll have to buy a replacement.

Tank maintenance can be hard work and takes its toll on plastic and rubber components, so always double-check that the water changer you’re considering buying is made from durable, high-quality materials.

Range of features

Some aquarium water changers offer additional features, such as multifunctional capability, extra-long hoses, or specially designed filters. Take the time to read the full range of features that each product offers before parting with your hard-earned cash.

One feature that’s especially important is that the device has the capability to fit on a range of faucets. For a water changer to work effectively, it must fit the faucet properly and without leaking. A fully adjustable faucet fitting can save you a world of pain in the long run.

Ease of use

The whole point of buying an aquarium water changer is that it saves you time and hassle when it comes to carrying out partial water changes and cleaning your aquarium substrate.

Check to see whether the product you’re considering buying is a plug-in-and-go device or whether it requires manual setup, which can be a hassle.

Size and hose length

The size of your tank will have a big influence on the aquarium water changer that you buy.

As a general rule, if you have a very deep tank, you’ll need a very powerful water changer that provides enough suction to pull the water out of the tank at a reasonably speedy rate. Also, if your aquarium is positioned some distance from the nearest sink that you can use for water changes, you’ll need to choose a product that has a long enough hose to comfortably stretch from the tank to the sink.

Final thoughts

Keeping your fish tank water clean and carrying out partial water changes every week is essential for your livestock’s health and well-being. Water changes and tank cleaning can be time-consuming, messy tasks at the best of times, and anything that makes the job quicker and less hassle is well worth adding to your fishkeeping kit. An aquarium water changer is an ideal gadget for that job.

All the aquarium water changers that we’ve reviewed for you in this guide are best-sellers, and all do a decent job. Choose a product that suits your budget, has all the features you want, and is easy to use, and you can look forward to quicker, easier tank maintenance.
