Why you should get a pond filter system
Basic Types of pond filter
There are three types of useful pond filter.
Submersed pond filter systems are easy to hide, although they take up valuable
space inside the backyard pond. They are usually attached to the intake side of the hose to trap particulates before they
reach the pond pump, thus protecting the pump as well as filtering the water. They come in different sizes and are usually fairly easy to
clean although the pond keeper will have to wade into the pond or in some other way retrieve the pond filter for cleaning, and waste may
spill back into the garden pond if not handled correctly.
In-line Pond Filters are usually self-contained canisters which are sealed and operated under pressure. They can be used submerged or above
ground.
External pond filter systems are the largest and best filters. They are located
above ground (or partially buried) somewhere near the garden pond. Water enters the filter from the pump and trickles
through several types of media to clean and de-toxify the water.
Although they need the least cleaning and provide the most ease of cleaning, the pond pump is not protected from floating debris because it
is placed before the pond filters. To protect the pump, it is best to attach a submerged pre-filter on the intake side
of the pump and an external filter on the output side.
There are new pond filter systems on the market now that are
“self-cleaning”. They have pressure chambers that can be squeezed out by turning a knob on the filter to compress the water out of the media
and flush the debris out the line. They are a great advance in pond-keeping.
Many of the pond filter systems today also contain internal UV sterilizers to help control algae.
