Most everyone will agree that a pond in one’s yard is a welcome addition to creating an atmosphere of peace and tranquility. A pond surrounded with beautiful plants and filled with fish and water lilies is a visual treat. To keep the water clean and the plants and fish healthy the pond needs to have oxygen pumped through it continuously. Pump manufacturers provide online tables to find the recommended pumps that they are producing.
The first step is to calculate how much water the pond holds. Other factors to consider are the waterfall and fish who will also require oxygen. The GPH or gallons per hour indicates how much water is pumped out in an hour. This number will serve as a guideline for choosing the pond pump. Another feature to look for is large intake slots so that there will be less blockage of leaves and other floating items. A five year warranty is also recommended in the event the pump was not properly installed or is a factory defect.
It is important to make sure that at least half the water in the pond is being circulated by the pump each hour. If the pond is small with about 200 to 1000 gallons of water a submersible pump would work well.
The external pump is a second choice. It is attached to the outside of the pond and is useful for pumping waterfalls. It is important to make sure that the correct filter is used with the corresponding pump.
A third type of pump is a solar pump. The advantage with solar is the savings in electricity as well as the convenience of no cords. This is a good backup option. Comparisons of the reviews of the different brands will help establish which brands are better than others.
