Water changes are the most time-consuming and cumbersome part of owning an aquarium. Depending on the layout of your home, it can mean lifting and carrying heavy buckets of water from room to room and may involve getting the occasional mouthful of aquarium water. In addition, the more difficult it is to perform water changes, the more likely you are to put off changing the water. And this can lead to unhealthy water conditions. Aquarium water changers make water changes much faster and easier and can reduce or eliminate the carrying of heavy buckets. Here are the best aquarium water changers.

Python No Spill Clean and Fill Aquarium Maintenance System, 50-Feet
  • Will not disturb fish or decor during routine aquarium maintenance.
  • Adapts easily to most faucets.
  • Complete ready-to-use system.
  • No buckets, no siphons, no mess, no tank tear downs ever again.

Python is the brand to beat aquarium water changers since they have such a simple and ingenious design. The Python No Spill Clean and Fill Aquarium Maintenance System uses a 50-foot hose (or choose the proper hose length for your needs) and a faucet attachment to drain aquarium water directly into your sink or drain to remove water.

Then, when you’re ready, simply reverse the flow and run tap water directly into your fish tank or into a nearby bucket for conditioning. This design means you never have to carry heavy buckets of water in your home again.

The Python No Spill Clean and Fill Aquarium Maintenance System works without disturbing fish or décor and is complete and ready to use out of the box. The adaptor quickly screws onto most faucets.

When you turn on the faucet, the valve creates suction that draws aquarium water along the hose into your sink for draining. When you reverse the valve on the Python adaptor, water flows outward from your faucet down the hose to your aquarium. This simple system is available with 25, 50, 75, or 100-foot hoses. So you can connect your fish tank to a sink in nearly any household.

The large siphon end allows you to easily vacuum your gravel and keep your aquarium clean without carrying buckets of water. If you have a specialty faucet, you may need to visit a local hardware store for the correct attachment, but it’s well worth it for such fast and easy water changes.

  • Makes routine water changes easier, eliminates spills and heavy lifting!
  • Attaches to faucet: removes dirty water and can return clean water
  • Vacuums out the debris in gravel right down the drain
  • Simply turn on your faucet to begin siphon
  • Be sure to add Aqueon Water Conditioner when adding clean water to aquarium

The Aqueon Aquarium Water Changer works in the same way as the Python. It attaches directly to a faucet and can empty water directly into a sink drain or draw water directly from the tap to your tank. It makes water changes incredibly fast and easy, with no mess, no fills, and no heavy lifting.

Since they work in the same way, the most significant difference between these two water changers is:

Python

  • More options in hose length
  • Replacement parts available
  • Higher quality construction, but more expensive

Aqueon

  • More universal attachment compatibility with sinks, faucets, garden hoses, etc.
  • More affordable but less durable

Buyer’s Guide – Best Aquarium Water Changers

When choosing an aquarium water changer, here are the key features to look for.

Hose Length

Depending on your home and your fish tank setup, a long enough hose may allow you to drain fish tank water directly into a sink or even outdoors. Consider how long you need your hose to be before choosing a fish tank water changer.

Pumping Mechanism

All the best water changers offer a better alternative for pumping than the old-fashioned mouthful of fish tank water. However, some use electric water pumps, some use manual pumping, and some use a faucet to create suction.

Electric pumps are fast and efficient but may not be durable and may break down over time. Manual systems may be a bit more tricky to master, and faucet-based systems may not work for the layout of your home. Each approach has its advantages, but determine what works best for your needs.

Flow Control Functions

Controlling the flow of water is an essential feature of a water changer. You may have fine sand or heavier gravel. You may have a small tank and want to empty it slowly and with precision, or a large tank that needs to be emptied quickly.

Or, you may spot a fish or large debris caught in the pump and want to promptly free it. Whatever the reason, while you can always manually control the water flow by crimping the hose in your hand, you may also want a water changer with flow control settings and functions to meet your needs.

FAQ

Can You Pump Tap Water Directly Into a Fish Tank During Water Changes?

Pre-treating your water for use in an aquarium is the preferred method. However, it is also time-consuming and usually requires the use of buckets. For faster water conditioning, you can use tap water, provided you take a few precautions. Here’s how you do it:

1. Allow your tap water to run for five minutes or so to remove any debris in your pipes.
2. Fill a glass of tap water and test it. You may want to test your tap water over a few days at different times of day to get an average. You may find that you have tap water that is dramatically different than your fish require, in which case you should not use untreated tap water directly in your aquarium.

If your water is within acceptable parameters for your fish, and you want to use it directly in your fish tank, follow these steps:

1. Let the water run for a few minutes to eliminate loose debris and impurities
2. Adjust the water to the right temperature for your fish (within 2-4 degrees is usually close enough). Use a thermometer to verify the water temperature.
3. Add an instant dechlorinator/water conditioner to your aquarium. Use as much product as you need for the amount of water you are changing. If necessary, err on the side of using too much product, rather than too little.
4. Use a hose to fill your aquarium from the sink with water that is approximately the correct temperature.

Final Verdict

The best automatic water changer for large fish tanks is the Python No Spill Clean and Fill Aquarium Maintenance System.
