魚缸不是近窗邊，為何出現青台．．．

Question

魚缸不是近窗邊，為何玻璃及木頭出現青台，有人介紹下就去買2條琵琶回來，但唔見效，又買了4條較細小精靈，但都唔見牠們(開工)，只啜玻璃．我魚缸30X10X12，ＣＯ２應該一分鐘釋放多少粒較合適，

Answer 1

你應該是有養水草對ㄅ?
如果有養水草ㄉ話就應該會有燈
魚缸會長青苔是很正常ㄉ因為青苔ㄉ生命力很強
琵琶鼠其實對青苔是沒什ㄇ作用
琵琶鼠是雜食性ㄉ如果當魚缸內沒有食物可以吃ㄉ話會反過來吃還活ㄉ漁
所以建議不要養琵琶屬
青苔是無法完全不讓他生長祇有方法抑制他生長比較慢而已
你可以減少開燈ㄉ時間並ㄑ水族館買專吃青苔ㄉ漁還有勤換水差不多一至二ㄍ星期換3/1ㄉ水還有把水溫提高到30度.....但是你有養水草ㄉ話不建議把水溫提高因為水草到30度會變ㄉ不是那ㄇ好看!
CO2最好是一秒1顆要看你水草ㄉ數量而定

Answer 2

Algae or moss (青台) grow in aquariums when there is a supply of nitrogen and light.
If it is placed away from windows, there is still light available.

You may want to check if you have a good control of the nitrogen, such a a filter to remove the excretion of the fish, which is rich in nitrogen, and/or changing the water in a regular basis.
