I was worried about product selection, but the drain hole was the correct type with this type.
For other goods, mud which you want to scoop will fall out.
Because I think that there is somewhat wider thing, it is decreasing by one star.
There is a drainage channel around the house, it is made up of two stages. The second stage which I purified was made with water of the pond → It made it to clean water, it was doing to vegetables etc, but I have not made it now. But · cleaning is necessary.

The purification layer is deep [for 2 steps] It is necessary to have 1.2 meters or more, I use it with a long hand.
