Answer: First you have to know how you got Algae in the first place then you can get rid of it.
All algae need three things to grow- an abundant supply of
nutrients; principally phosphates and nitrates. Sunlight in
great amounts ties it all together. Knowing this should make it
easy to control Algae.

The fastest and easiest way is to do water changes; this washes out most of the nutrients. Plants can be added to the pond to compete with the Algae for nutrients. (This can also be done in a bog filter) Also some kind of a sun sail will help.
Sun Sails are easy to install temporarily blocking the sun; A UV light will help on a continuing basis, but it must have a slow rate of water flow to kill the (Plankton) Algae. Then the dead Algae will be filtered out in the system.

Get someone at the store where you buy it to figure out how big a unit you need.
There are also chemicals to add to the pond to kill Algae, but use them as only last resort. The goal is to "control" algae- not kill the algae entirely.
Don’t forget you are the one who doesn’t like Algae, the Koi love it.
