Whenua diatomaceousKo te tātari he taahiraa matua ki te hanga pono, pumau hoki o ngā hinu huawhenua, ngā hinu kai me ngā hua kai e pā ana.

Whenua diatomaceousHe māmā ngā āwhina tātari, he koretake ngā matū, ā, he nui te porowhita o ngā keke tātari hei pupuri i te rere noa o te wai. Ina koa, ko ngā āhuatanga o tētahi āwhina tātari whai hua ko ēnei e whai ake nei:

Me whakarite te hanganga o ngā matūriki kia kaua e piri tahi, engari kia hanga he keke he 85% ki te 95% te āputa o ngā pūwero. Ehara i te mea ka nui ake ngā tere rere tuatahi, engari ka whakaratohia hoki he āputa hei hopu me te pupuri i ngā totoka ka taea te tātari, me te waiho i te ōrau nui o ngā awaawa kia tuwhera mō te rere.
