為什麼需要過濾?
分解水中有毒的代謝物---->生化過濾(石英球、陶瓷環...等)
濾掉水中雜物 ---->物理過濾(白棉、羊毛絨、活性碳...等)
PS.
大部分濾材都有2種以上的過濾效果
但為了方便管理及效果最佳化
依所需搭配不同濾材
-----------------------------------------------------------------------
上部過濾
濾材放在魚缸上方的盒子裡
利用馬達將水抽至濾材上方經濾材到魚缸
優點:過濾能力強、清洗方便、便宜
缺點:外觀不好看、佔魚缸上方空間
底缸過濾
多設一個底部缸在魚缸下方
濾材放下方底缸裡
在魚缸設置一排水孔讓水流至底缸
再由馬達抽水至上方魚缸
優點:過濾能力最大、可藏魚底櫃裡、安靜
缺點:貴、佔空間
底部過濾(底抽)
在魚缸底部放置浪板再蓋上底沙
接一馬達或打氣機的出風口(氣動)在浪板出水口
水由魚缸中向下流經底沙至浪板再流到出水口到缸中
底沙擔任生物過濾的濾材
優點:過濾能力大、便宜
缺點:清洗濾材麻煩、須定時吸底沙
-----------------------------------------------------------------------
圓桶過濾
利用虹吸原理將水抽到魚缸下方的圓筒
圓筒裡擺濾材
再由圓筒的馬達將水抽至於缸裡
優點:安靜、過濾過程中不會曝氣(空氣與水攪動)
缺點:貴、空間不大
水妖精
水妖精接打氣機出風口
裡用白努力原理將水妖精旁的水吸至中央再向上排出
水妖精周圍的生化棉就是濾材
優點:便宜、增加溶氧量、清洗方便
缺點:過濾效果不好、吵
外掛
類似縮小版的上部過濾
優點:便宜、清洗方便、可調整曝氣量
缺點:過濾效果差
還有其他過濾方式但原理大同小異就不列出來了
像背部過濾的過濾方式就有點像底缸過濾
-----------------------------------------------------------------------
過濾效果
一般而言
底缸>上部>圓筒>=底部>外掛>=水妖精
-----------------------------------------------------------------------
總結
過濾方式沒有好壞
依照所需選擇過濾方式就是好的過濾
一般而言
超高水質要求
海水軟體缸----->底缸
高汙染
中大型魚或高密度養殖----->底缸、上部
高CO2需求
陽性草缸----->圓筒
弱水流環境
短雕----->氣動
防止吸入馬達
繁殖幼魚幼蝦----->氣動
沒特殊需求的小缸推薦外掛
