- Why does my pump not pump water? To ensure the water pump operates properly, the following steps must be taken: Submersion Requirement: The pump must be fully submerged in water. Inlet Clearance: The water inlet should be at least 50mm below the water surface. Air Removal: For the first startup or after water replacement, gently shake the pump to expel any trapped air inside.

The Ultimate Buying Guide for Your Fish Tank Water Pump
Choosing the right water pump is vital for a healthy and happy aquarium. A good pump keeps the water clean and moving, which fish need to thrive. This guide will help you select the best pump for your tank.
Key Features to Look For
When shopping, focus on these important features:
- Flow Rate (GPH – Gallons Per Hour): This tells you how much water the pump moves in one hour. You usually want to turn over the entire volume of your tank 4 to 6 times every hour. A bigger tank needs a higher GPH.
- Head Height (Max Lift): This is the maximum vertical distance the pump can push water. If your filter or waterfall is high above the water, you need a pump with good head height.
- Energy Efficiency: Look for pumps with low wattage. They save electricity and often run cooler.
- Adjustable Flow Control: Some pumps let you easily dial the flow up or down. This is great for fine-tuning the environment for sensitive fish or small tanks.
Important Materials for Durability
The materials used directly affect how long your pump lasts and how safe it is for your fish.
Pumps for Freshwater Tanks:
- Most standard pumps use durable plastic housings.
- Look for ceramic shafts in the impeller area. Ceramic shafts resist rust better than metal ones and last longer.
Pumps for Saltwater Tanks:
Saltwater is harsh. You must choose carefully:
- Look for pumps made with high-quality, corrosion-resistant plastics or titanium components. Avoid cheap metals that will quickly break down in salt water.
Factors That Improve or Reduce Quality
Not all pumps perform the same. Pay attention to these factors:
What Makes a Pump Better?
- Quiet Operation: Good pumps use magnetic drive technology (mag-drive) or have rubberized bases to reduce vibrations and noise. Nobody likes a noisy tank!
- Easy Cleaning: Pumps with easily removable intake screens and impellers last longer because you can clean out debris regularly.
- Thermal Protection: A safety feature shuts the pump off if it overheats. This prevents the motor from burning out if the water level drops too low.
What Reduces Pump Quality?
- Cheap Bearings: Pumps with low-quality internal parts wear out fast, leading to loud noises and eventual failure.
- Overheating: Running a pump dry (without it submerged in water) quickly destroys the motor seals.
User Experience and Use Cases
Where you plan to use the pump matters greatly.
Submersible vs. Non-Submersible (External) Pumps
- Submersible Pumps: These sit entirely underwater inside your tank or sump. They are generally quieter and easier to install for basic filtration. Most hobbyists use these.
- Non-Submersible (External) Pumps: These sit outside the tank and suck water up through a tube. They often handle very high flow rates needed for large sumps or external reactors. They can be noisier.
Common Uses
- Filtration Return: Moving clean water from a sump back into the main display tank.
- Powerheads: Small pumps placed inside the tank to create water movement, helping oxygen reach all areas and preventing dead spots.
- Fountain/Waterfall Features: Creating decorative water movement in specialized setups.
10 Frequently Asked Questions (FAQ) About Fish Tank Water Pumps
Q: How often should I clean my fish tank pump?
A: You should clean your pump every one to three months. Mineral buildup and slime reduce performance quickly.
Q: Can I use a pump meant for dirty water (like a pond pump) in my fish tank?
A: No. Pond pumps often use materials that are not safe for aquarium inhabitants. Always use a pump specifically rated for aquariums.
Q: What is the “head height,” and do I need to worry about it?
A: Head height is how high the pump can push water vertically. If your filter is much higher than your tank water level, yes, you must check the head height rating.
Q: Will a strong pump harm my small fish?
A: A very high-flow pump can create too strong a current. Use the adjustable flow control feature or a powerhead designed for low flow if you keep small or weak-swimming fish.
Q: Do I need a separate pump if I have a hang-on-back filter?
A: Hang-on-back (HOB) filters have their own built-in impeller/pump mechanism. You only need an additional pump if you are adding a separate feature like a protein skimmer or a large wave maker.
Q: What is the best way to reduce noise from my submersible pump?
A: Make sure the pump sits firmly on the bottom and is not touching the glass. Many pumps come with small rubber suction cups—use those!
Q: How do I know if my pump is energy efficient?
A: Look at the wattage listed on the box. Lower wattage for the same GPH means better efficiency.
Q: What happens if my pump runs without water?
A: This is called “running dry.” It causes the motor to overheat quickly, which melts internal seals and destroys the pump very fast.
Q: Are magnetic drive (mag-drive) pumps better than direct-drive pumps?
A: Mag-drive pumps are usually quieter and safer because the impeller is magnetically coupled, reducing the need for complex seals that can leak or wear out.
Q: Does the pump size depend on the type of fish I have?
A: The pump size primarily depends on the total volume of water you need to clean (GPH). However, the *type* of fish affects how much flow you want—sensitive fish need gentler flow.
