acceptable levels, depending on
temperature and stocking levels.
Bacteria grows faster in warm
water. E.g. a pond at 5 Celsius will
have a very low bacteria count
and a slow growth rate. Therefore
temperature is important in reduc-
ing the time for a bacteria colony
to develop.
Bacteria require food to live otherwise it will starve. The
food for bacteria is liquid and solid waste produced by
fish. Therefore higher stocking levels will provide more nu-
trients for the bacteria and help it to establish a colony.
The liquid waste is called ammonia and is the food for
the bacteria. Solid waste is broken down to ammonia,
but a Koi keeper is better off removing the solid waste
through settlement. The fitting of an Answer 325 filter into
your Nexus 200 filter will improve this dramatically.
The ammonia reducing bacteria, nitroso-monas, pro-
duce an end product called nitrite, which is again
potentially toxic to fish. This is controlled through estab-
lishing a large nitrobacter population to convert nitrite
to the end product, nitrate. The effect of nitrate is less
harmful than both ammonia and nitrite. However if
nitrate levels are allowed to rise above 50 mg/L pond
keepers may start to experience green water & blanket
weed. The Kaldnes Moving Bed Process™ is very useful
in controlling these levels as it has the
highest removal rate of any submerged media on the
market.
