Water Hyacinth

I am now placing water hyacinths on the soil.
It seems that no one is eating them.
They appear to be high in fiber.

The fish eat their roots and hide in them.
I am watching the water hyacinths which grew in water where I keep fish, go through the process of becoming soil.

Egeria Densa

By the way, I do not eat water hyacinth.

Even if I put creatures in a container filled with water, they cannot survive.
I need to supply what the creatures need and remove what is unnecessary.
Usually, in an aquarium, food is given, water is filtered through a filter, and oxygen is supplied through aeration.

I make a water plant circulation with water hyacinth and egeria densa.
If the container is placed in a sunny location, the roots of the water hyacinth release carbon dioxide, the egeria densa absorbs it and releases oxygen, and the water hyacinth leaves also release oxygen.
The creatures living there eat the plants and their humus, and breathe oxygen.
And they provide movement to prevent water from rotting, and give nitrogen and carbon dioxide.

In winter, since microbial activity is absent, the water is clear.
This is a magnificent circulation world formed by the water container and the creatures within it.

What I want to say is...
When growng aquatic creatures, do not grow water hyacinth to completely fill the container.
When make clean water for terrestrial creatures, grow them densely.

And their cultivation must be strictly limited to your own property, because they are very tough.

Water Hyacinth

I always need to be able to maintain edibles in my own space.
So, I keep trying various hydroponics.

Water hyacinths are one of the toughest floating aquatic plants, and they're basically edible.
They reproduce very vigorously and absorb oxygen and nitrogen from the water.
If they become dense, no other creatures can live there.

In other words, they can safely remove water decay in a short period.
That's their special power.

Surprisingly, this is the outdoor container oryzias cultivation.
