Quite A Few Things You Have To Take Into Consideration When Selecting A Fish Pond

Pond pumps are a necessity if you have a fish pond. Pond pumps can also be used to create wonderful effects in your water garden. Pumps are great for creating waterfalls and fountains and will provide needed oxygen to all the life in your pond. There will be several things you need to take into consideration when purchasing a pond pump.

One of the first things to think about is the flow rate you need for your pond. The minimum flow rate that you should get will be approximately half the volume of water in the pond. If you have a pond which holds a thousand gallons of water you should choose a pond pump which will circulate a minimum of 500 gallons every hour. If you have lots of additional water features you may need one with a greater flow rate.

The pond pump that you select will need to move enough water to meet the demands of your UV sterilizer and filter system. The function that you pond plays will also help determine which solar pond pump is right for you. Ponds which are small to medium in size, holding up to 800 gallons of water, do best with a submersible pump. They can be easily attached to submersible filters used in this pond size.

The flow rates for submersible pond pumps are around 250 to 4,100 gallons an hour. These pumps are fairly inexpensive and work inside the pond. The start up costs with these pumps will be low but they will cost more to run than an external pond pump. Large ponds will need the flow rate that only an external pump can provide. You will find that external pumps have greater energy efficiency and can handle a large volume of water. They also work very well with biological filters which produce pressure which can put strain on a pump. The typical flow rates for external pond pumps run around 1,800 to 7,000 gallons per hour.
