上個月初設了一缸兩呎標準缸,60x30x36
主要養燈魚、鼠魚,
沉馬原本用了eheim新的1000L的那顆馬達
買了才發現被騙 其實上面只有850L
但是因為要打上部過濾,算下來揚程約120cm
果然一試用發現像老人尿尿流超慢,
於是又買了一顆eden 140,
然後把eheim那顆裝旋轉頭來造流,
現在問題是,感覺缸內水流似乎有點太強,
魚是沒有什麼異狀只是感覺會一直被水流吹的往後退,
但燈魚吃東西什麼都正常,飼料一丟也會搶食,
鼠魚則是愛吃不吃,無時無刻都在吃砂裡的殘屑,
有時候會跑去衝浪,或是打氣機的氣泡衝浪
我看了一下eden 140那顆沉馬的曲線圖,
揚程120cm似乎還有2200L/H的流量,
我是用仿底濾式的那種上部過濾,
出水管超大一根約43mm
感覺馬達全開水量也不多, 落水聲還是很大聲,
後來塞了一點白棉在出水口,讓管內出水速度變慢,
整根管子塞滿水,就沒什麼聲音了,
但有一天發現水流太慢,過濾盒太滿淹出來,
於是又把白棉拆掉,繼續讓它吵,
以現在的流量換算下來等於每小時循環32次,
好像大家都建議每小時循環10次就已經很多了,
也就是600L/H,想請問我該調小我的出水量?
到底怎麼判斷水流是否有太強?
謝謝各位前輩指教!
