Keeping a fish tank is not just about having beautiful fish; it’s also about creating a healthy and balanced environment for them to thrive- you don’t want to mistreat the fish! One of the critical components in achieving this balance is the fish tank water pump. If you’re a tropical fish guy like me, you know that selecting the right equipment can be both exciting and overwhelming. This article aims to demystify fish tank water pumps and help you choose the best one for your wet pets.

Understanding Fish Tank Water Pumps

What is a Fish Tank Water Pump?

A fish tank water pump is a device that helps circulate water within your aquarium. It ensures that the water remains oxygenated, distributes nutrients, and maintains a consistent temperature throughout the tank. Essentially, it mimics the natural water flow found in rivers and lakes, providing a more natural habitat for your fish. Not the EXACT same thing as a filter– but many times a filter can serve as a pump.

Types of Fish Tank Water Pumps

• Submersible Pumps– Submersible pumps are designed to operate underwater. They are ideal for small to medium-sized tanks and are relatively quiet. Since they are submerged, they do not require much space and are easy to conceal within the tank’s landscape.
• External Pumps– External pumps are placed outside the tank and are connected via hoses. These are typically more powerful than submersible pumps and are suitable for larger tanks. They can handle higher flow rates and are easier to maintain without disturbing the tank environment.

Choosing the Right Fish Tank Water Pump

Factors to Consider

• Tank Size– The size of your tank plays a significant role in determining the type of pump you need. A small tank might only require a simple submersible pump, while a large tank would benefit from a powerful external pump to ensure adequate water circulation.
• Flow Rate– The flow rate, measured in gallons per hour (GPH), indicates how much water the pump can move. It’s essential to match the pump’s flow rate with your tank size. A general rule of thumb is to aim for a flow rate that can move at least four times the volume of your tank per hour.
• Noise Level– Nobody wants a noisy aquarium pump disrupting the tranquility of their living space. Submersible pumps tend to be quieter, while external pumps can vary in noise levels. Look for pumps that advertise quiet operation if noise is a concern for you. My wife is CONSTANTLY complaining about this… so, happy wife-happy life- get a quite one!

Installation and Maintenance Tips

• Installing Your Water Pump– Installing a water pump might seem daunting, but it’s quite straightforward with the right guidance. For submersible pumps, place the pump in the desired location within the tank, ensuring it’s fully submerged. Connect the power supply and check for proper water flow. For external pumps, follow the manufacturer’s instructions carefully, connecting the hoses to the inlet and outlet, and securing the pump outside the tank.
• Maintenance Best Practices– Regular maintenance is key to the longevity and efficiency of your water pump. Clean the pump’s intake and impeller regularly to prevent clogs. Check for any signs of wear or damage and replace parts as needed. Keeping the pump clean ensures optimal performance and prolongs its lifespan.
