| presently I'm running bakki shower exposed to the sunlight, and japanese
filter media heavily oxugenated from way below the media in covered (dark)
vortex filters upflows ( 3 ) I also run a small portion thru a trickle filter of bio balls.
It is definetely over kill for my koi but since i use my pond as an educational facility for visitors, it's fun to have more than one going at anyone time. Don't laught but I have half as much water into filters as the volumn of the pond. |
