Frequently Asked Questions (FAQs)

1. Can I use submersible pump in aquarium?

Submersible aquarium water pumps draw in water through a filter to produce clean water that is sent back into the aquarium. Basically, they are a must-have for aquariums as they are essential to the health of your aquatic pets and their environment.

2. How do I choose an aquarium submersible pump?

The pump lift is about 1.15-1.2 times the height of the lifting water. For example, if the height of your aquarium is 1m, you should choose a water pump which has a 1.15-1.2m pump lift. Pump flow refers to the amount of liquid that the pump delivers per unit of time.

3. How do submersible aquarium pumps work?

Bubbles displace the water, stirring it and sending the carbon dioxide to the surface. External pumps move the air via a hose attached to the pump that is dropped into the water. Water pumps are submersible and work by creating a current, or movement, in the water.
