Materi penelitian adalah probiotik akar, tangkai daun dan daun Eceng Gondok yang ditempatkan dalam aquarium dengan volume 20 liter dan ditambah probiotik 10ml. Metode penelitian adalah metode eksperimen skala laboratorium.Hasil penelitian menunjukkan bahwa rata-rata konsentrasi bahan organik tertinggi yaitu 55,23 – 60,21% pada akar, 51,14 – 54,71% pada daun dan 46,60 – 50,54% pada tangkai daun. Kadar nitrat tetinggi yaitu 1,102 – 3,238 mg/l pada daun, 0,555 – 1,969 mg/l pada tangkai daun dan 0,313 – 1,200 mg/l pada akar. Kadar fosfat tertinggi yaitu 0,014 – 0,142 mg/l pada daun, 0,008 – 0,100 mg/l pada tangkai daun dan 0,001 – 0,067 mg/l pada akar.
