Aquarium enthusiasts know the importance of reliable water pumps for maintaining healthy tank environments. In this review, we’ll delve into the performance of various water pumps, comparing their actual output to their manufacturer claims. We'll test flow rates, maximum lift heights, and power consumption to see which brands hold up and which fall short.
The Contenders
We tested the following pumps:
1. Seabillion HY303: Claims 800 liters per hour (L/h), 8 watts.
2. Seaquest 800: Claims 800 L/h, 12 watts.
3. Switch SW7: Claims 800 L/h, 7 watts.
4. Aquaspeed A1100: Claims 1100 L/h, 7 watts.
5. Seabillion HY304: Claims 1500 L/h, 10 watts.
6. Aquaspeed A2000: Claims 2000 L/h, 13 watts.
7. Seaquest 2200: Claims 2200 L/h, 25 watts.
8. Switch SW35: Claims 2500 L/h, 25 watts.
Why Flow Rate Matters
The right flow rate is crucial for different types of aquariums:
- Saltwater aquariums: Require 10-15 times the tank volume per hour.
- Reef tanks: Need 20-40 times the tank volume per hour.
- Planted tanks: 3-5 times the tank volume per hour to avoid disturbing plants.
- Freshwater fish tanks: 4-6 times the tank volume per hour for efficient filtration and oxygenation.
Calculating the Flow Rate
To calculate the required flow rate for your tank, simply multiply your tank volume (including filter water) by the recommended turnover rate. For example, a 20-gallon freshwater tank should have a pump that circulates 80-120 gallons per hour.
Testing Methodology
We used a 15-gallon container and timed how long each pump took to fill it at a 1.5-foot lift, simulating a typical tank setup. We also measured power consumption using a power consumption tester, running each pump for an hour to calculate monthly costs based on local kilowatt-hour rates.

Summary
Our tests reveal that most pumps fall short of their claimed flow rates but perform adequately for specific tank setups. It's essential to choose the right pump based on your tank size and desired flow rate, considering both the lift height and power consumption to manage operational costs effectively.
Conclusion
Choosing the right water pump for your aquarium is crucial for maintaining a healthy environment. Our tests show that while many pumps don't meet their claimed specifications, they can still be suitable for specific tank setups. Always consider the actual performance and power consumption when selecting a pump to ensure the best results for your aquarium.
