ʻO ka hoʻohana ʻana i nā paipu kila i hoʻopaʻa ʻia i loko o ke ola o nā kānaka. No laila, ʻike anei ʻoe i nā māka e hiki ke hoʻokaʻawale ʻia i ka maikaʻi o nā paipu kila wiliwili nui-anawaena? E ʻae mai iaʻu e hoʻolauna iā ʻoe i ka ʻike kikoʻī ma lalo nei.

ʻO ka mea maʻamau, ʻo ka ili o ka ʻili wela o ka nui-anawaena pololei hili ʻia ʻana o nā huahana kila paipu ʻo FA, a ʻo ka ili o ka pickled nui-anawaena pololei hili ʻia ʻana o nā huahana he FB. ʻO FB/FC/FD nā huahana i hoʻopaʻa ʻia i ke anawaena nui.

ʻAʻole i loaʻa i nā huahana kiʻekiʻe nā koi ili maʻamau. No ka laʻana, hoʻohana nā panela i loko o ka kaʻa i nā ʻaoʻao FB. No kekahi mau panela waho o nā kaʻa ʻaʻole i kiʻekiʻe nā koi maʻamau, e hoʻohana iā FC. No nā kaʻa kiʻekiʻe, e hoʻohana i ka FD surface.
