水草情迷

[問題] 鐵釘可以當鐵肥用嗎？
係泥底放小量鐵釘，有用嗎？對d魚有害嗎？

kees, 那應該是可以呵

No, it cannot.

某程度上,對綠色水草而言,是可以的.
但對紅色水草則一定不能提供足夠的鐵肥.

No, it will not help at all. All you do is watch it to rust away.

的一段資料:

"The nutrients must also be present in a form that it useable by the plants.
Your query about "iron rust" indicates that you might not be aware that rust
is iron oxide which isn't directly useable by plants as a source of iron.
Organic acids and bacteria can, over time, convert some of the iron into a
form useable by the plants but only under certain conditions and a much
easier and more direct route would be to use something like Flourish Iron."

因此,我是相信鐵銹在某程度上是可以提供鐵肥的,
但絕對不能提供足夠的鐵肥給水草.

鐵銹唔係會對缸內生物有害架咩..?

我的魚缸資料(2008-5-13更新)

Are we here to offer practical answer or thoerical word game? Practically, an iron nail in a planted tank will just rust, and do nothing else. Besides, the chemical/biological reaction mentioned does NOT take place in oxygen saturated open water.

唔好玩啦

少到=無，不如唔好放

以前好似看過有關文章講過,又話一價鐵又話二價鐵,總結是生銹鐵水不等於鐵肥
