It was my narcissism and joy. Id spent three months salary on imported Ohko stone and high-grade ADA Amazonia soil. I felt past a king. That is, until I realized my "king" setup weighed as much as a baby elephant. I hadnt used an aquarium weight calculator back then. I just assumed "Its forlorn water, right?" Wrong. certainly wrong.
