Pengalaman saya pernah melakukan percobaan tanaman air thypa sp. dgn menggunakan bak fiber yg dialiri air limbah dr PDPAL setiabudi selama beberapa minggu,hasilnya tanaman tsb mengalami perbesaran lbh cepat dibanding dgn air biasa. Setelah dibawa ke lab ternyata air tsb byk mengandung fosfat yg menyebabkan tumbuhan cepat besar..
