[問題] 養硝化菌技巧,如果係新開缸.....
要幾耐先換一次水...

d 棉係唔係唔駛換架?

thanks

From 3 weeks to 2 months, depending on size of tank and number of fish/shrimp inside. So there is no fix answer.

Do not put fish or very little because they die pretty easily during that time.

No need to change water (or change very few).

NEVER Change the cotton! These are the "beds" for the good gems.

You may buy testers for NH3 and NO2. When both indicates zero consistently that it is time that the cycle has stabilised. Then you may gradually add fishes in small batches.

Please read more from by searching 硝化菌. Please please please.....

What if I only change to a new tank, but use the old water?
Can I put in everything immediately, have no need to wait?

(In fact, the only change is just new tank and soil, but old filter, fishes & grass.)

Emm...in your case, probably wait very little time to stablise. The Gems are attached on the filtering stones/cottons inside the filter.

Unless there is another factore that kills all the gems. Never done this before....so i am only guessing

一開頭係必定要放魚， 但量要很少， 同一路要 check 住水質， NH3 或者 NO2 上升太多便要換水。 沒有生物既缸係永遠唔會建立硝化系統。

七蟲草， 如果做得好， 又用回舊既濾材， 係可以做到對硝化系統無重大影響， 不過頭一兩個星期一樣要詳細觀測水質。

NH3/NO2/NO3 kit 其實係好重要， 好多資深既養家都會用， 唔係唔會通處都有得賣啦， 買番套看門口吧。

其實三個 Testing kit，有三個讀數，都是用來 test 缸內硝化系統的，o甘..只用一樣得唔得呢？

定是三個讀數在唔同變化，係有唔同的意思？

如果你個缸係保持係 pH 6.5 以下， 咁 NH3 就唔係咁重要， 可以唔買， NO2 係最毒， 最好有， NO3 係植物主食一種， 太少會草唔靚加起藻， 太多又會起藻， 一些草需要特定既 NO3 量先靚， 可能比人少或多， 草缸必備。我就習慣保持NO3 係 10 - 20 之間， 有經驗後都好小用， 係見到一些問題， 好些椒草開始溶， 或者突然多左好多浮萍呀咁。

Thank You.
O甘我要整番支 NO2 至得啦！因我只有 NO3。
想再問問 NO3 係唔係永遠去唔到零？因我未見過我的缸的 NO3 是零的！

想問問, 我的草缸好快有藻, 是否同 NO3 高有關

My humble opinion: No fish means slower (a lot) to have the N-cycle stablised. But decaying /dead leaves are also a source to generate NH3/NH4 and thus establishing the N-cycle.

Frankly I don't mind put just 2-5 cheap little fishes as the "heros" because they won't die so easily. But some people may not like this. Fishes are living thing- not to be risk for their lieves. It's a personal choice , I think.

what is the equipment used for testing for NH3 and NO2 ?
where and how much about it.??

thanks

Go to fish street. Ask them...they will show you.

Cost you within $200. (or less)

The box has clear labelled "NO2 Test Kit". Each set with a test-tube with a small bottle of tester liquid. Really like back to school in chemistry lab... :p

Good luck!

If you know what you doing, and monitor the water parameter properly, there is no reason for fish to die during cycling process. Often, fish that cycle my tank out live late comers because they're usually a little more hardy.

Decaying leaves, and other decaying matters won't produce enough N for cycling, in fact, the downside is that presence of plants will counter the effect because live plants would readily take NH3/4 as preferred source of nitrogen, in practice, if you plant very heavily, cycling won't start even with small number of fish because plants simply use up all the N as soon as it is available. If you want to do a fishless cycling, the common method is dump ammonia directly into the tank daily, until the tank is cycled. But it certainly won't do any good for just an empty tank without any animals or ammonia supplement.

Don't forget that nitrification system depends on waste load as well. An established system simply means it can handle the current waste level, not more. A plant only tank will certainly develop some kind of nitrification process, because no matter how much N that plants aabsorb, in thoery there will always be a very small amount of N left in water, and a very small amount of bacteria can live on that. But bacteria colony will always stay small because there is simply not enough food for them to grow, that kind of nitrification system, no matter how long you wait, will never be large enough compare to a properly established system.

爆藻同NO3無直接關係，反而磷先係藻的最愛，太重肥同過多飼料才是主因。
