Pond Filter Flow Pattern

There are many ways to find instructions and patterns for making a homemade koi pond filter. If you belong to a garden pond club or society, you may come in contact with someone who has made their own filter.Before you can make your own homemade pond filter, you will need to understand the different types of filters and water flow.



1. Horizontal Flow Patterns

One thing is certain and that is a river situation is the most ‘natural’ flow pattern of all these applications. However, it is best that we briefly consider all these flow patterns yet again in order to find out why there has to be ‘a best of the bunch’ and, if so, just how much ‘better’ it is than the others. Once again, if we must admit that we will never have true perfection here then it is very wise to consider using the very best alternative available to us. I feel that covering all these methods in fine detail is of GREAT importance despite the fact that many consider them to be ‘long-winded’.


2. Downward Flow Pattern

It did just that and remained captive inside the media until the various hitherto ‘easy routes down’ became blocked with accumulated mechanical debris. This caused the falling water to find an easier series of routes to take and so on. If this was left unattended, all the routes became blocked and so the water simply found an exit over the top of the box and spilled over onto the garden


3. Upward Flow
Some of these guises are pump-fed with gravity return; gravity-fed with pump return; surface side exit; surface central exit; surface trough exit; circular upward-flow patterns; multiple chamber units; aerated fluidised media systems and many other variations. Again, these relate to a body of water moving upwards in any given container/box.
