Aquarium Water Pump
An aquarium water pump is one of the most crucial pieces of aquarium equipment. It's one task is to move water. Aquarium pumps can be used in sump filters, inside the aquarium for circulation or in some cases externally. Aquarium water movement requirements are different between a freshwater fish tank and a saltwater fish tank. There are many different views on the proper turnover rate. As a general rule of thumb, a freshwater aquarium should turn the total water volume over 4 to 5 times an hour. In a saltwater aquarium the rate is higher at 6 to 10 times an hour. Select the pump that will turn your aquarium over the proper volume per hour.
