hi cool_ice59 ,
Your topic on Biological Filter vs Mechanical Filter is very interesting, and in comparing the effectiveness on both as a standalone filter can be quite difficult.
Biological filter, serves as a system that regulates your water property ie; your ph measurements, nitrate measurements, nitrite, measurements, amonia contents and all those nasty bi-products coming from kois waste "tahi" and the left over food. A biological filters performance can be measured on how much bacteria it can cultivate in reducing all these things. These bacteria needs alot of space to grow on, and oxygen to survive on in order to be effective. Research the topic of "Nitrogen Cycle" and you will have a rough idea of how filters work. Also check out Bakki Showers and Trickle Towers as they are both Biological filters and requires less maintenance.
Mechanical Filters, on the other hand removes all unsightly things in your pond without relying too much on bacteria cultivation. They require constant cleaning and monitoring so that it performs effectively. Unlike Biological Filters, Mechanical filters does less of an efficient job in controling the ph, nitrate, doc, nitrite, amonia measurements in your water. What they do is to simply create an appearance of good clear water. Products like Eazy pods, Sand Filters, etc are what you call mechanical filters.
