水草情迷

a). 請問除NO2 和 NO3 是否用以下的濾材呢?
b). 是否兩種濾材可以放在同一個濾桶內呢?
c). 這兩種濾材是否用了一段時間就要更換呢? 還是可以長時間放在濾桶不需要更換呢?
請各位 C hing指教!

這兩種濾材是否用了一段時間就要更換呢? - I think so

I prefer to use digestive bacteria to decomposite NO2 and NO3
.....i usually add it every week...

哦! 原來消化細菌可以取代我用的兩種濾材. 但消化細菌是否有化學成份呢? 如果有化學成份, 會否影響水晶蝦生長呢? 請多多指教!

睇下以下文章有無幫助!?

Aquarius兄, 好多謝你的資料.

消化細菌 is growing in natural environemnt which helps to build the nitrogen compound decompsotion cycle. it's natural and no harm. The artifical one only increase their growing speed and don't worry. U can do more search in this forum......

哦! 原來消化細菌是沒有化學成份, 資料很詳細, 謝謝你的幫忙!

U're welcome!

There're several types of 消化細菌 (oxygen like / dislike). They're very important in the nitrogen fixing cycle in aquarium tank. Highly recommend to search n read some old posts as they'll help U to save a lot of fish life ^_^

it should be 硝化細菌 rather than 消化細菌
雖然意思上可以咁解

Yes yes.....thx
