Pond Filtration Putting It Simply

There are two main types of successful pond filtration.

An ULTRA VIOLET filter kills green water to keep the water clear, while a BIOLOGICAL FILTER looks after the water quality to keep the fish healthy and happy. Most modern filters combine these methods into one unit for convenience and ease of installation. It is recommended to use a biological pond filter if you are keeping koi carp or any pond fish.
