要解釋硝化系統，就不得不提起臭名昭著(zhù)的氨氮、亞硝酸鹽——兩種對于魚(yú)兒有毒的物質(zhì)。在我們喂食的飼料、魚(yú)兒的排泄物和分泌物中，含有大量的有機氮，這些有機氮氨化后會(huì )形成氨氮。而氨氮通過(guò)硝化作用轉化為亞硝酸鹽，亞硝酸鹽再通過(guò)硝化作用轉化為硝酸鹽，這個(gè)過(guò)程就叫做魚(yú)缸中的“硝化系統”。</span></p> <p

style="font-size:18.7px;"> 一般來(lái)說(shuō)，魚(yú)友們對于氨氮和亞硝酸鹽是比較忌諱的，因為這兩種劇毒的“氮”一旦含量過(guò)高，魚(yú)兒分分鐘就會(huì )“翻肚皮”。</span></p> <p class="MsoNormal" style="margin-top: 0em; margin-bottom: 15.65pt;

style="font-size:18.7px;"> 而對于硝化系統的最后一步——硝酸鹽，大家往往會(huì )忽略它的危害。雖然硝酸鹽短期毒性不大，但長(cháng)期積累到一定量后，依然會(huì )對魚(yú)兒的生長(cháng)生活帶來(lái)壓力，造成慢性中毒。特別對于養海缸的魚(yú)友們，硝酸鹽過(guò)高會(huì

針對硝酸鹽，我們就要提到魚(yú)缸“氮循環(huán)”的另一個(gè)部分——“反硝化系統”。簡(jiǎn)單來(lái)說(shuō)，就是將硝酸鹽和亞硝酸鹽通過(guò)反硝化作用，轉化為氮氣排出水體的過(guò)程。這個(gè)過(guò)程中，硝酸鹽還原為亞鹽、硝酸鹽轉化為氮氣、亞硝酸鹽轉化為氮氣的三個(gè)步驟，會(huì

<span style="font-size:18.7px;"> 魚(yú)缸中建立起了完整的硝化和反硝化系統，氨氮、亞硝酸鹽、硝酸鹽三種“氮”含量才能降到零。那么如何建立起魚(yú)缸的硝化和反硝化系統？這里就要提到構建起系統最重要的橋梁——細菌。硝化系統中，起到硝化作用最重要的“硝化細菌”，相信大家都不陌生。它是一種好氧類(lèi)的自養型細菌，魚(yú)缸中附著(zhù)在濾材和底沙上繁殖，生長(cháng)周期比較慢，與異養細菌競爭時(shí)容易造成生長(cháng)受限，因此依靠自然培養的硝化細菌去除氨氮效果較弱，這時(shí)我們就需要引入硝化細菌來(lái)提升水體硝化能力。</span></p>
