1. Te horoi tere i te wai: Ka taea e ia te wawahi tere i te haukini, te hauota nitrite, te hauwai pākawa me ētahi atu matū konganuku taumaha, te tango i ngā haunga, me te pure i te wai.
2. Te tere o te whakatipu huakita: mā te maha o ngā hanganga moroiti ā-roto ka taea te whakanui ake i te nui o te hāora rewa i roto i te wai, ā, ka pai ake te wāhi whakaputa uri mō ngā huakita whakanitrogen.
3. He pai te mimiti: Ka taea e ia te mimiti tere i ngā paru ika, ngā toenga, me ētahi atu, ka pirau, ka pure i te wai, ā, ka whakarei ake i te ārai mate o ngā ika.
4. He pai te uruhanga wai: ka whakaohooho pai i ngā ngota wai, ka whakatairanga i te pirau me te whakanui ake i te nui o te hāora i roto i te wai, ka whakapai ake i te pūnaha tohanga moroiti, me te whakatairanga i te pākia o te ika. 5. Te whakahinuhinu pāmahana teitei: ka whakahinuhinuhia te kōhatu puia, te kōhatu hauora me te fluorite i te pāmahana teitei, he nui ngā kohuke me ngā huānga iti, he pai ki te whakau i te uara PH me te whakataurite i te kounga o te wai.
