The Best Way to Keep Your Koi Pond Clean is With Pond Filters

Written by jerrysplace on May 9, 2011 – 12:31 pm -

Not every pond needs filters but every pond that contains fish needs a pond filter.  Pond filters do more than clean the water.  They keep the eco balance of ponds, clean the water, and provide the needed oxygen koi need to survive.  Although, if you look at Mother Nature’s way of controlling ponds you’ll see you do need a pond filter.

If we follow the way Mother Nature takes care of her ponds then we can see she supplies ponds with water, air, and nutrients to keep the pond’s ecosystem balanced.  The same can be applied to your koi pond with a pond filter.  Depending on the type of filtration, a pond filter can keep a pond in top condition 24 hours a day.

Pond filters come in all sizes and shapes.  They can run 24 hours a day or be put on a timer to run several times a day or 10 minutes every hour.  It depends on the type of pond you have for the type of filter you need.  Plus, it depends on the number and size of fish, whether they are koi, goldfish, or even trout.

There are pond filters that filter out the debris and algae while inserting oxygen into the water.  Oxygen is needed not only for the fish to breath but for plants to grow as well.  The more fish you have to more oxygen you’ll need to keep them healthy and alive. The filter pump can be submersible or sit on top of the water such as a waterfall with a built-in pond filter, usually called an external pond filter.

A pond filter system in a complete system you need to keep your pond’s ecosystem intact. They come with filtration, pump, skimmers, baskets, filters, and filter media.  They also include sand or rock or other types of filtration media.  Filtration media can be rock, carbons, zeolites, ion-exchange resins, aluminum sulfate, and other types of media.  They remove the “junk” or bad biological bacteria from the water.

Fish waste consists of ammonia.  Too much ammonia and it eats up all the oxygen in the water and your fish will die from lack of air to breath.  Pond filters not only clean the water of ammonia but they also clean out bad bacteria while increasing good bacteria and oxygen — The main essentials for a healthy koi pond.

You can purchase pond filters fully ready to install or individually components of a filter system (as replacement parts, too).  They also have pond filter kits you can put together for your pond.  You can hire a professional to install your pond filter system or get your best friend to do it for you.

Most of the kits come with everything you need for your pond.  All you have to do is install it and turn it on for it to start working.  The price range for filter systems can run from $20 to hundreds of dollars depending on the size of your pond.

To insure your koi have a long life and remain healthy be sure to use the right size pond filter for the amount of water your pond contains.  If the filter system is too small it won’t be able to keep up with the debris from the pond or the ammonia from the fish. Always use the next largest size filter that you think you need. Most manufacturers have a calculator to figure what size is needed according to the gallons of water in your pond.

I personally run with two filters, one pumps from the skimmer and the other pumps from the bottom of the pond. I like the idea of pulling the water from two separate sources in the pond. The one is a biological filter with media and the other is a pad type filter which requires more cleaning than the established biological filter. I hope my insight into filtration helps you with your decisions to purchase a filtration unit.
