A filter
system that removes all mechanical debris and waste on daily
basis efficiently.
|
|
A pond
depth of minimum 5 feet to cut down harmful temperature
fluctuation.
|
|
Partial
water change (10%) daily. Keep nitrate level as low as possible.
|
|
To have
maximum oxygen content, at least 8ppm.
|
|
No over
stocking (not too many fish).
|
|
No over
feeding.
|
|
Sunshine
30% to 40%. A shade or cover is ideal.
|
|
High
level of nitrate and subshine can promote algae blooms, known as
green water. To have up to 10% and 20% water change daily
over several days until level of nitrate is reduced.
|
|
In
tropical climate, koi are more active and readily eating food.
This s in turn generate more waste and toxicity which most of
the filter system cannot deal with, thus resulting in rapid
deterioration in water quality. We can quickly be faced with a
situation where parasites and bacteria are multiplying rapidly
adversely affecting the health of our koi. |
