The Essential Fish Tank Pump Buying Guide
A fish tank pump is a vital piece of equipment for any aquarium. It keeps your water moving and healthy for your fish. Choosing the right pump makes a big difference. This guide helps you pick the best one for your tank.
Key Features to Look For
Several features matter when you select a pump. Think about what your aquarium needs most.
Flow Rate (GPH)
Flow rate is how much water the pump moves per hour. We call this GPH (Gallons Per Hour). Most experts suggest you should turn over your tank’s entire volume at least four to five times every hour. A bigger tank needs a higher GPH pump. Check the pump’s specifications for this number.
Head Height
Head height is the maximum vertical distance the pump can push water. If your filter is high above the water level or you have a very deep tank, this matters a lot. If the required height is more than the pump’s head height, the pump will move less water than advertised.
Noise Level
Loud pumps can annoy you and stress your fish. Look for pumps that mention “quiet operation” or use terms like magnetic drive technology. Read user reviews about noise before buying.
Energy Efficiency
Pumps run all day, every day. A more efficient pump saves you money on electricity bills over time. DC pumps are often more efficient than older AC models.
Important Materials
The materials used in the pump affect how long it lasts and how safe it is for your fish.
- Pump Housing: Most quality pumps use durable, non-corrosive plastics. This plastic should be aquarium-safe and not leach harmful chemicals into the water.
- Impeller: This is the spinning part that moves the water. Ceramic shafts are generally better than stainless steel shafts because they resist rust and wear out slower.
- Cords and Seals: Make sure the power cord is long enough and the seals are tight to prevent leaks.
Factors That Improve or Reduce Quality
Not all pumps are built the same. Some things make a pump great, while others cause problems.
Quality Enhancers
- Variable Speed Control: This lets you adjust the flow rate. This is great for fine-tuning the water movement for different life stages of your fish or plants.
- Easy Cleaning: Pumps need regular cleaning to remove algae and debris. Pumps with easily removable intake covers and impellers offer better long-term quality.
- Built-in Air Stone Port: Some pumps include an extra nozzle to connect an air stone, letting you add aeration without a separate device.
Quality Reducers (Things to Avoid)
- Cheap Motors: Motors that overheat quickly wear out fast. This reduces the pump’s lifespan significantly.
- Suction Cup Failure: Poor quality suction cups will detach, causing the pump to fall and rattle against the tank bottom.
- Brushes (in some motors): Pumps using carbon brushes might create carbon dust, which can contaminate the water if the motor housing fails. Magnetic drive pumps avoid this issue.
User Experience and Use Cases
How you plan to use the pump changes what you should buy.
Submersible vs. External Pumps
Submersible pumps sit inside the tank. They are usually quieter and easier to install. They work well for simple filtration setups or water circulation.
External (or inline) pumps sit outside the tank, usually beneath it. They often handle higher flow rates and are common with canister filters. They require plumbing connections.
Use Cases
- Small Desktop Tanks: You need a very low GPH pump, perhaps under 50 GPH, and maximum quiet operation.
- Large Saltwater Reef Tanks: These require powerful pumps (powerheads) to simulate ocean currents, focusing on high flow and durability.
- Sump Systems: These rely on high head height pumps to lift water from the sump back up to the main display tank.
Frequently Asked Questions (FAQ) About Fish Tank Pumps
Q: What are the main Key Features I must check?
A: You must check the flow rate (GPH), the maximum head height, and the noise level. These three things determine if the pump fits your tank’s size and location.
Q: Do I need a submersible pump or an external one?
A: Submersible pumps go inside the water and are simple. External pumps sit outside and handle more power, often used with large filters. Choose based on your setup’s complexity.
Q: How often should I clean my fish tank pump?
A: You should clean your pump at least once a month, or whenever you notice the water flow slowing down. Debris clogs the impeller quickly.
Q: What does “magnetic drive” mean?
A: Magnetic drive pumps use magnets to spin the impeller instead of direct physical shafts. This design usually means less friction, quieter operation, and no risk of carbon dust contamination.
Q: Can a pump that is too small still harm my fish?
A: A pump that is too small won’t harm them directly, but it will result in poor water quality. Without good circulation, waste builds up, which can make fish sick.
Q: What material is best for the impeller shaft?
A: Ceramic shafts are generally the best choice. They resist corrosion and wear much longer than standard metal shafts.
Q: How do I calculate the correct GPH for my 20-gallon tank?
A: Multiply the tank size (20 gallons) by four. So, you should look for a pump with at least 80 GPH to ensure good water turnover.
Q: Is a noisy pump a sign of a broken pump?
A: Not always, but excessive noise often means the impeller is hitting something, or the motor is struggling. It usually signals that the pump needs cleaning or is starting to fail.
Q: Should I buy a pump with variable speed control?
A: Yes, if possible. Variable speed control lets you adjust the flow. This is very helpful if you have delicate fish or live plants that need gentle water movement.
Q: Does the power cord length matter?
A: Yes, it matters for safety and convenience. Make sure the cord is long enough to reach an outlet without needing a risky extension cord or being stretched too tight.
