Misunderstandings of making waterand making a pond
by Mr.Kazuya Akasaka
| Blind men pass their hands over an elephant.
There are words in a sacred book of Buddhism
that blind men pass their
hands over elephant.
This is an anecdote warning that judging whole figure of an elephant by touching parts of the animal leads us to misunderstand the real figure.Then, what is the condition of pond water to keep Nisikigoi?
Every person who keeps Nisikigoi knows the wards"making fish is making water".As same as air is necessary for human, water is necessary for fish because water is total environment for them. Therefore,keeping Nisikigoi has to start from making pond water for fish to live healthy.
However, asking pond owners"what condition of water is suitable for Nisikigoi?"they give me various answers.One owner says,"My pond has clear water, which is best".Another says,"Water of my pond is best, because it is within standard when the water was examined"
In addition, another is proud saying"My
pond has assimilated good water,
so, my koi eat much and their swim is excellent"
Answers are various, but common position is that pond water is judged by
only one phenomenon.
| What is good water?
Different from fish-breeding ponds, concrete ponds of fanciers are for
seeing koi.Therefore, clear water is essential condition, which is a matter
of course.On the base of it, pond water in which koi can grow healthy is
good life water.
In such water, as"always to be healthy
is the first condition"their koi grow
naturally"far from illness".
Illness free carps swim and eat well,
it is guaranteed that koi get big growth.
As healthy koi secrete slime much, which protect their body,mucous membrane
of the skin gets thick and reflects glossily. Therefore, we can appreciate
koi in a pond better.
First, fanciers' common request is
koi' beautiful figure in a pond.
Further, considering from breeder's position,
cleaning free (labor free) pond is desirable.
"Making pond with low cost"is also
Further,"no maintenance cost"is nice for pond owners.In short,
ponds, which need small initial cost and running cost is best.
| Not by filtration but by purification
Without making a good pond, good pond water
can not be obtained.
Without making good pond water, good koi
Great number of various kinds microorganism live in purification tank under
in good balance.We have to understand the fact that the earth is based
on activity of microorganism.Koi and microorganism live symbiotically balancing
both in quality and in quantity.
"To live symbiotically" means to live together getting benefits
each other.Therefore, making a pond is nothing but setting up a suitable
purification tank,and is not to construct an exaggerated filtration tank.
Filtration is to filtrate materials as the word means,but purification
is"to make microorganism owe role to purify water".
I hope difference between purification and
filtration can be realizing.
Details of purification will be mentioning
gradually from next time.
Please put the feel into your understanding that pond water should not
be clearing through filtration but be made suitable condition for koi'
lives through purification.
I wish you to say good bye to the past misunderstanding.
Then, how such a pond should be made?
My business is to design using basic know-how (Refresh System) of pond and purification tank.
So far, I have been designing more than one
I have also been designing many times for
reforming existing ponds.
Construction of ponds is done by my partners.
| Making ponds in foreign countries
I have been worried to know through English magazine for Nisikigoi
and talking with others that filtration are taken too many in making ponds
in foreign countries on the base of many misunderstandings.
I do not know where these misunderstandings
come from. Recently,
stress has been building up in me,because I have to press down my feeling
to go there and correct their way of making ponds.
