Pressurized filters are now the most popular choice among do-it-yourself pond owners.
These filters can be partially buried and run under pressure allowing them to direct filtered water up to the top of your waterfall. With this kind of system there is no need to have an unsightly filter box at the top of your falls!
Most pressurized filters can also be purchased with a built-in UV clarifier for crystal clear water without the use of chemicals.
