Before you begin your pond construction you will need to determine the type of pump system your pond will need. Pond pumps are designed for many applications and there are a number of parameters that a pond pump must meet satisfactorily. Some people buy two pumps so that they can use one for a fountain arrangement and the second for the filter. That way they know that they have bought the correct pump for the correct purpose. First of all decide what the purpose of the pump will be. Do you want to use it with an internal or external filter, a fountain, or waterfall?
If you are using a pump for a fountain, it is important that the pump have a prefilter. Without a prefilter the fountain head will get blocked up and require cleaning all the time. A pump that will be used for fountains does not need to be powerful because they are not required to move huge volumes of water, therefore they are less expensive than a filter pump.
The main pump, which is the filter pump, will be the most expensive pump you will have to buy for your pond construction. The main pump works with a filter and should be able to pump small solids of 0.12 to 0.16 inches without becoming clogged. Because filter pumps do not have a prefilter, the dirty water can be moved quickly to keep the pond clean. If you try to use a pump for filter that wasn’t made for filtering you may have problems because it will become clogged in the prefilter or it just will not be able to keep up with the volume of water and then you will have a dirty pond.
When choosing a pump you need to purchase a unit that has the correct flow rate and capacity for your pond. The general rule of thumb for this is that the volume of your pond should be circulated through the filter every two hours. Because the pump is so important to the health of your pond, this is one area that you do not want to skimp on.
