水草情迷

PSB即係咩呀???

THZ~

光合成菌, 淡水用.

Be careful that many unexpensive 活性碳 do release phosphurs which in excess do cause algae. And it also absorb trace elements.

哦~
我落左硝化細菌ja~
其實係咪同一樣野泥架???

咁唔用活性碳有咩可以取代

買黑珍珠啦

我都係個句.........等

唔好落敢多化學

is 黑珍珠 = Active carbon or they are same subsitance?
Because some people said active carbon will release the absorbed material when they become saturated. If 黑珍珠 contained active carbon. it may need to change within 2-3 week

then use 竹炭 law, it will not release harmful substances.

咸淡水都有,分解有機物,多數要厭氧環境
