O le su'esu'ega masima fa'alesoifua maloloina o la matou su'esu'ega autu ma atina'e galuega ausia, fa'atasia fa'atasi e le Chinese Academy of Sciences ma Frankstar. O le meafaigaluega e faʻataʻitaʻiina atoa le faʻaogaina o le tusi lesona, ma e naʻo le tasi le meafaigaluega e mafai ona faʻamaeʻaina i le taimi lava e tasi le mataʻituina i luga ole laiga o ituaiga e lima o masima faʻalesoifua maloloina (No2-N nitrite, NO3-N nitrate, PO4-P phosphate, NH4-N ammonia nitrogen, SiO3-Si silicate) ma le maualuga maualuga. Faʻapipiʻiina i se faʻamau faʻapipiʻi, faʻafaigofieina le faʻatulagaina o faiga, ma le faʻaogaina faigofie, E mafai ona faʻafetaui manaʻoga o le vaʻa, vaʻa ma isi faʻataʻotoga fanua.
