Best Submersible Aquarium Pump FAQ:

Q1: What if my submersible water pump does not work?

A1: Each submersible pump undergoes a separate tank test to ensure the highest quality. If your submersible pump has problems within 2 years of purchase, you can come back to us and we will be responsible for the pumps we produce.

Q2: How does the dry burn protection function work?

A2: There is an intelligent temperature control chip inside the submersible pump. If the pump runs without water, the temperature of the chip will increase, and then the power will be automatically cut off to protect the pump and power supply. After the power is turned off, the chip has cooled down, put the pump back into the water, and the pump will continue to work. This function can not only ensure the safety of electricity use, but also save your money to buy water pumps.

Q3: What size submersible aquarium pump do I need?

A3: As a general rule of thumb, you should aim for your pump to be capable of turning over the volume of water in your aquarium five times every hour. First, establish how many gallons your tank holds. Then multiply that by five to get the minimum flow rate in gallons per hour (GPH). So for a 180 gallon tank, you will need a pump that is capable of producing at least a minimum flow rate of 900 GPH.

There are other factors that may affect the flow rate, though. These might include elbows and turns in the plumbing, for instance, or fitted filters. That’s why it’s always better to opt for a pump that has a slightly larger flow rate than you think you need. If your pump is too weak, it’s impossible to increase water flow.
