Tips for choosing

Quality

The internal parts of the air pump should be made of some metal, rather than plastic, because over time, it can release particles into the hydroponic system.

Size

The size of the air pump will depend on the size of your hydroponic system. A good rule of thumb is for the pump to deliver at least 500-600 cc (500-600 ml) of air per minute.

Also, as a general rule of thumb, 1 watt is needed for 1 gallon of water. Therefore, for a 5 gallon tank, a minimum of 5 watts is required.

Nozzles

For large hydroponic systems with many plants or multiple tanks, a pump with multiple nozzles is required.

Tubes

Aquarium tubes are very functional. It is important that these have dark colors to avoid the proliferation of algae. Another option is to wrap the tube with black adhesive vinyl.

Noise

You can opt for a pump below 45 dB for comfort. Also, you can place a pad underneath to muffle the noise.

Operating time

For deep water culture systems, the pump has to run all day, every week.

Security

  • You must plug the pump into a wall outlet and not into a surge protector.
  • Place it in a cool area to avoid overheating.
