Biological
filtrationNitrification
is a biological process during which
nitrifying bacteria convert toxic ammonia nitrate.
Sources
of pollution
Often there is a failure to
understand just how rapidly and to what degree koi pollute the
water they live in.
Organic
Pollution
This form of water pollution
indirectly affects koi health by encouraging high levels of
opportunistic bacteria and parasites, as well as affecting overall
water quality.
Removing
solids from the system
If we could remove the solid wastes
from the system before they had chance to dissolve and pollute the
water we would have better water quality, less dissolved
pollutants and fewer health problems.
Biological
filtration & filter media
What's the difference between the
sometimes bewildering and conflicting claims made for various
filter media?
Flow rates
& retention times
Although a detailed understanding of
filtration mechanics is not essential, this page does explain why
some filters work better than others. There are a lot of
over-stocked koi ponds with pretty poor filtration systems.
