ʻO ke kinikini kānana kānana kaila keramika

ʻO ke kinikini keramika me ke one quartz kiʻekiʻe e like me nā mea maka, ma hope o ke kalina wela kiʻekiʻe, me nā waiwai kemika paʻa. ʻO ka quartz sand filter material, acid acid & alkali resistence, uncontaminated, high density, ikaika load load. ʻO ke aniani ceramic ring me ke kiʻekiʻe o ka pore permeability pore, hiki ke hāʻawi i kahi ākea kikoʻī nui no ka hoʻopili ʻana o ka hoʻomaikaʻi ʻana i nā koʻohune, e hoʻoliʻiliʻi pono i ka amonia a me ka nitrite i loko o ka wai. waena
