Water flows from the water source.Using the water supply in this biotope, it has always been made to water flows. We manage this biotope and will intend to observe it in future. 
The water flows through the brook and finally arrives at the pond.
This brook winds windingly, and various creatures live in the puddle on the way.
It is a pond of the biotope, but algae spreads and is very dirty.Why will only algae increase without waterweeds increasing? 
A dragonfly came over. We did not understand the kind, but it was very fast and had a hard time to put it in the camera. 
There was an American crawfish.It is that American crawfish said to be an aggressive naturalized species. We considerably increase in the pond. June 11 
Because the algae of the pond was too bad, We decided to clean it. 
It looks like we clean the pond together. We saved algae soon and took out a cancer outside a pond. 
It looks like a cancer consumes algae and sludge soon. If porcelain cancer made of bamboo than iron reblogged it is scooping easy to feel. June 13 
It looks like two days passed after cleaning.Most of the dirty algae disappeared. 
We came to see underwater prawns and crawfish clearly.
