Fertilizer Dosage : Inspired by the trails and mountains of East Java where I hike regularly, I try to move the beauty and the serenity of nature to my living room. I am elaborating on every detail that I find in the wilderness in this aquascape work. By emphasizing the stream as the focal point of my work, I put forward this philosophy: "Life is a stream that flows by so quickly; happiness and sorrow come and go day by day. Making each moment count is the best thing we can do to embrace the blessings of life."

Additional Information
Traveling deep into the dense forests of Yakushima, I came across a very interesting tree. The tree exposed the ground in countless layers of roots as if it were its own age, and lived slowly and powerfully for many years. What's even more interesting is that the folded roots are partly exposed to direct sunlight, and there is no moss in those parts. The moss, which is not covered with clothes, is also beautiful, and I wanted to express the deep mountain and secluded valley of Yakushima with this interesting tree as the main character in the aquascape.
