This filter box has a large square hole at the bottom, allowing water to flow directly without obstruction. Water at the edge of the hole cannot flow to the outer edge of the hole because of the water barrier attached to the slot at the bottom of the box with glue.

Perforated pipes are pipes that have many holes on the left and right sides and use a cover as a water retainer that is tied with a cable tie, at the end of the pipe is closed with a 13mm rubber cap.
