| Well Carl that is the kinda of innocent arrogance I'm talking about. That is not an insult by the way so don't be offended. It is an innocent perspective that often creates quirky corrections to problems that shouldn't exist to begin with. I can name ten of them that have come, been THE answer and then disappeared on these many koi boards in the last ten years. It's all fun. Fun for people- if only the koi didn't have to go through it with their keepers/tormentors.
The koi filter core function has not changed in 60 years. And certainly the bacteria that runs them has not changed in a 1000 years. Man's vanity certainly has not changed in 10,000 years.
The very first 'bioreactor' in koi ponds were gravel beds. Either IN the pond, or outside the pond. This was both a mechanical and biological filter for managing inorganic and organic pollution. It then was refined, and refined again to manage organic and inorganic pollution. From trapping the inorganic material to removing it. From needing massive space for nitrification to becoming so efficient that less space was needed. This is not change to a 'new concept' this is the evolution of one concept.
Koi keeping teaches humility. I find the newbie to be, at times, the least humble of all. The fertile ground that produces the innocent arrogant.
