Koi filters: best biomedia Japanese matting; best design vortex filters

Koi filters dedicated to growing large koi are not the same as for garden ponds needing simple small koi filters or plain simple box type bio filters. Koi ponds tend to be deep and high volume. Large koi eat lots of food. Large koi need extra oxygen and a highly efficient koi filters design with equally efficient biomedia in the koi filters to cope - the ideal is japanese matting inside a vortex filter.

Koi filters design especially vortex types of koi filters needs very special attention.

Please note here that I am talking about the koi enthusiast – people who build 10,000 gallon ponds and buy very expensive koi or grow small koi up to big koi. They must have great koi filters I am not talking about homemade water garden pond filters for the small koi pond enthusiast who has a pond of about 2,000 litres (500 gallons) or less.

Koi Filters

I am taking this opportunity to dissuade people from using sand filters for a koi filters even as so called "polishing koi filters". I do want to prompt the real enthusiast go in the direction of vortex koi filters using japanese matting or something similar.... they are genuinely the best.

I am also not going into any details about specific design criteria. I will give my views based upon my chemical engineering knowledge and discussions with world leaders in the koi field (or should it be koi pond?) like Nigel Caddock and Peter Waddington over many years.
