How to get rid of algae in a koi pond.  This question is the most common one heard by pond professionals and enthusiasts.

Learning how to get rid of algae in a koi pond doesn’t have to be as difficult as you may think. Having the right tools and techniques at your disposal will go a long way.   The green pond battle can certainly be won.

There’s nothing more tranquil and relaxing than listening to a waterfall running into a garden koi pond. On the flip side, there’s nothing more frustrating than having this Zen-like image ruined.  Murky green pond water doesn’t cut it for most people.  You need to see your fish to be able to enjoy them.

In this video, I’ll show you a few successful methods of dealing with this unwanted marine plant. I’ll discuss the use of ultraviolet (UV) filtration as well as methods of removing string or filamentous algae.

Filter Start-up

As you can see in the video, it is the start of the new season and the water is dirty.  It’s warming up enough here and it’s about time I get my filter going.

The winter season and freezing temperatures are tough on connections and piping joints.  Tightening connections is a easy maintenance habit to embrace.  I always recommend grabbing a screwdriver for a quick pond walk-around.

We’re going to get the filter running and see how quickly we can get it working to start cleaning up the pond.

Following these techniques will quickly bring your pond back to its original clear state.

Learning how to get rid of algae in a koi pond is easier than you think.  Trial and error works but UV clarification certainly speeds up the process.
