水草情迷

目前參差不齊的商品陳列在坊間，消費者實在很難用品牌去斷定你買到的到底是不是真的硝化細菌，在此提供大家一個科學實驗的方法，來試試看自己手邊的硝化細菌到底是真是假，方法如下：

1.取氯化銨粉末極少量，溶於500ml水中，當成母液。
2.取5cc母液用氨/銨測試劑（如:TBS廠牌）測氨/銨濃度紀錄之。
3.將硝化細菌產品加入母液中。
4.若干天後，在取樣測定氨/銨濃度，看母液的氨/銨濃度有否明顯降低，若有則為硝化細菌真品，若無則為假貨。

此方法提供給大家，大家有時間的話都可以用科學的方法去判斷你買到的到底是真硝化細菌產品，還是假硝化細菌。

Hi TBS,
Would u like to tell us which brand must be the real one? so we no need to test ar !
Thank you

There are 硝化細菌 anywhere, even on the air.
So with enough food ammonia, 硝化細菌 can growth very fast.
I am wondering your test is valid only if you can create a non-bio environment.

Agree with alder.
Test is only affirmative when a strict set of test protocol is used (like in a properly setup lab at my Univ) AND with a well design control.

Just put a dead fish in a container and leave it aside somewhere long enough (not add bacteria), tons of nitrifying bacteria will still grow in it.
