Filters For A Backyard Fish Pond

Last summer we put in a Koi Fish pond in our backyard, overall we were really happy with it but we ran into issues finding filters that would keep our pond environment in good condition and the fish healthy.

This site about Koi filters is just what the doctor ordered.  There is plenty of information about buying and even making your own filters for your Koi pond. 

One this to be sure of is the gallon rating if you buy a filter.  If you buy too small of a filter for your size pond you will have to replace the filter frequently and it may not work properly.

Just some tips before buying or making your own filters!
