如何正確養魚?

有無必要在魚缸水中放化學品? (如水質安定和硝化細菌......)

硝化細菌的主要功能係唔係只係使水更清潔,對魚的幫助唔大?

活性碳又有咩用?要點樣用

如果D 魚只在水底流,極少上水面,代表咩?

過多氧氣會唔會有害?

    有病先放好化學

    硝化細菌係清細菌

    活性碳主要是用作為氣體或各種物質選擇性吸附的基材,用途廣泛,上自化學品、醫藥品的生產製程,下至廢水處理、含戴歐辛(dioxin)之廢氣處理等環保領域,也用於淨水、廢水處理、甜味料脫色、化學、醫藥和礦物加工、食品加工、空氣或其他氣體吸附純化與溶劑回收。一般而言,目前活性碳在水質的處理上大約佔其用途的80%,包括30%用於飲用水、22%用於工業及都巿廢水、12%用於甜味料之脫色、地下水用7%、礦物用5%、家庭用約5%、食品加工用約4%,以及其他包括化學製程的雜項約佔有11%;至於在氣體上的用量約佔其20%,包括5.8%用於空氣淨化、5%用於溶劑回收、4%用於汽車,以及其他包括香煙濾嘴的雜項約佔有5.2%。

    活性碳因碳的形狀與性質而有不同的應用領域。粉狀碳主要應用於化學品純化/脫色、水處理、飲料淨化、精製糖、製藥及食用等液相製程;粒狀碳除了可用於液相外,也可用於氣體吸收、溶劑回收、金的回收等氣相應用;蜂巢狀及纖維狀碳則多使用於大空間低濃度的氣相中,如吸附空氣中VOCs(有機揮發性化合物)或毒性物質的濾網、影印機或室內空氣淨化器用除臭濾網等;纖維狀碳尚可做成口罩、防護衣及濾水器之濾心等。

    活性碳市場的活絡主要來自環保議題的驅動,尤其是水和空氣污染的處理,這種現象在先進國家中特別明顯,而其他傳統用途的用量,也以2~3%的比例逐年增加。目前各大活性碳廠商也均朝向氣體分離用、回收汽車之汽油蒸汽(gasoline vapor)、電子材料等精密且高附加價值之領域與活性碳摻混製程方面加速發展,一方面也可彌補應用在泛用品領域逐漸萎縮的利潤。

    佢唔上水 冇咩問題 係D水高/你個放魚既地方大

    過多氧氣可能冇問題

    但正常就ok

    Hello there! I am Derek Tong, I hope I can help you with my own experience

    1. 有無必要在魚缸水中放化學品? (如水質安定和硝化細菌......)

    In my opinion, I dont think u have to put in medication unless your fish are suffer from specific disease. 硝化細菌 can be produced in the sand after a short period of time, usually better grown with plants in the water.All you need to do is provide a comfortable and natural environment for your fish.

    2. 硝化細菌的主要功能係唔係只係使水更清潔,對魚的幫助唔大?

    Yes, it helps a lot to the fish, they act as a cleaner under the sand where they get rid of most of the dirt in the sink. 1st responser explains better in his answer.

    3. 活性碳又有咩用?要點樣用

    It helps to pure the water to a higher extent as one of its function is used to treat polluted water. For me I put it in the 濾水器 in case the fish accidentally eat it.

    4. 如果D 魚只在水底流,極少上水面,代表咩?

    According to my experience, this means they are not used to the environment, but this means there are plenty of oxygen in the sink. Keep observing for a period of time, if nothing changed, try to put some fish toy or plant in the sink, fish like swimming through holes, if still not help, then i think u need to seek some further advice in a fish shop.

    5. 過多氧氣會唔會有害?

    No, fish grow better when more oxygen, because it is easier for them to breath, but when there is too much oxygen then there is a risk of putting plants in the sink or otherwise plant will release the a higher amount of CO2 in the sink. So fake plant are appropriate for you case

    Hope this can help!! If you have any further question, feel free to e-mail me!!

    Best wishes,

    Derek
