Thx Leo 兄 for your information,
again this article concern mainly on 水產養殖, but not aqua plant. There are also some questions

轉載自其他網頁:
水中的的氨有兩個不同的形式:一是氨 ( NH3 ),另一是銨 ( NH4+ )。但在酸性的水中,有毒的氨幾乎不存在。
if ADA soil, used, the water in aqua planted tank will be acidic, so 有毒的氨幾乎不存在........so, no need to use 硝化細菌...
Leo Wong 寫:
在養殖池中存在的有毒物質主要是氨及亞硝酸,這兩種有毒的物質可由硝化細菌所消耗,並生成無毒性的硝酸,硝酸又是藻類的最佳氮肥,能被藻類所吸收及同化。
so, 硝化細菌 can make more fertilizer for 藻類?......then more 藻類?......
Leo Wong 寫:
市售硝化細菌製劑可分為活菌及休眠菌兩種,漁友可依自己的需要選購使用。前者是利用細菌的活體製成,在顯微鏡的觀察下,可看到它們的活動情形。後者是利用休眠菌製成,在顯微鏡的觀察中,則無法看到它們具有活動能力。
but from another article in this site

"
None of the Nitrobacteraceae are able to form spores. They have a complex cytomembrane (cell wall) that is surrounded by a slime matrix. All species have limited tolerance ranges and are individually sensitive to pH, dissolved oxygen levels, salt, temperature, and inhibitory chemicals. Unlike species of heterotrophic bacteria, they cannot survive any drying process without killing the organism. In water,
they can survive short periods of adverse conditions by utilizing stored materials within the cell. When these materials are depleted, the bacteria die...."
if this is true, then both 活菌及休眠菌兩種 are impossible to be stored for selling more than a few days......
still, Nitrobacteraceae do nothing on PO4, PO4 is also a main reason of algae.....
