Koi Pond Filters

Why do we NEED to have a filter on Koi Ponds?

Most beginners believe pond filters work by removing physical dirt and this keeps the water sparkling clean.

Unfortunately this is not the case, although a small amount of waste will be strained from the pond as it passes through the filter.

The most important part of the filters job is to act as a mini sewage system for the pond. In simple terms the media within the filter creates a huge surface area, which becomes home to many millions of helpful bacteria.

When physical waste such as fish waste, excess food or decaying organic material fall to the bottom of the pond it starts breaking down and releasing toxins into the water. As the water passes through the filter the helpful bacteria break down these invisible toxins and any other organic waste which get caught up in the filter.

More advanced filter and pump systems will strain out more solids from the water, but it must still be remembered the filter has to biologically break this organic waste down, and the most dangerous toxins are invisible to the eye. Clear water does not mean healthy water!

Hence it is vital to purchase a filter, which can easily cope with your pond volume and anticipated fish stocking level! Please always check the capacity of your chosen filter to ensure it suits the size of your pond.
