The Roles of Wave-Making Pumps and Submersible Pumps in Aquariums

Wave-making pumps and submersible pumps are both essential tools in the world of aquariums, especially for those who keep large fish species like Arowanas and Koi. While they may seem similar, their functions and proper usage can vary significantly. Here’s a detailed look at each type and how to use them effectively:
Wave-Making Pumps: Creating a Dynamic Environment
Wave-making pumps are widely used in aquariums housing large fish species such as Arowanas and Koi. These fish often develop short and stocky bodies when kept in still water environments, which can detract from their natural beauty. Wave-making pumps address this issue by creating artificial currents and waves that mimic the natural flow of rivers. This encourages the fish to swim against the current, showcasing their graceful movements and maintaining their elegant body shapes.
Moreover, the artificial currents generated by wave-making pumps significantly increase the oxygen levels in the water. This enhanced aeration promotes the circulation of beneficial microorganisms, which is crucial for the overall health and growth of the fish.
Key Considerations for Wave-Making Pumps:
Flow Rate: It is crucial to select a pump with an appropriate flow rate. Too high or too low a flow can be detrimental to the fish. The ideal flow rate depends on the size of the aquarium and the specific needs of the fish species.
Safety: The intake of the pump must be protected to prevent fish from being sucked in. This not only avoids injury to the fish but also prevents blockages that can cause the pump to overheat and potentially burn out or cause electrical hazards.
Submersible Pumps: Driving Filtration Systems
Submersible pumps are primarily used to facilitate water circulation and filtration in aquariums. Their main function is to draw water from the tank and transport it to a filter system, where it passes through various stages of filtration before returning to the tank. This continuous circulation helps maintain water quality and ensures a healthy environment for the fish.
When using a submersible pump for filtration, it is recommended to choose a pump with a flow rate that is 3 to 5 times the total volume of the aquarium. For example, if your aquarium holds 100 liters of water, a pump with a flow rate of 300 liters per hour would be ideal. This ensures efficient filtration without overwhelming the system.
Key Considerations for Submersible Pumps:
Flow Rate: As mentioned, the flow rate should be proportional to the aquarium’s volume. A pump that is too weak will not provide adequate filtration, while one that is too powerful can stress the fish.
Safety: Similar to wave-making pumps, the intake of submersible pumps should be equipped with a large mesh cover to prevent fish from being injured or trapped.
Conclusion
While wave-making pumps and submersible pumps may fall under the broader category of aquarium pumps, their functions and proper usage differ significantly. Wave-making pumps are designed to create dynamic water currents that enhance fish health and aesthetics, while submersible pumps are primarily used to drive filtration systems. Both types of pumps are essential for maintaining a healthy and vibrant aquarium environment, but their effectiveness depends on careful selection and proper installation.
By understanding the unique roles of these pumps and taking the necessary precautions, aquarium enthusiasts can create a thriving habitat for their fish.
