水草情迷

請問缸底發熱線是否養草的重要設備?用後會否明顯增加水溫?請各位分享分享.

其實以香港氣候不需要用底床發熱
不過如果你想做對流效果...
亦都可以這樣做

那麼以缸底發熱線做出對流的效果是否對水草及整缸的生態有重要的幫助?因小弟看過一本水草種植的書,作者認為這個裝備是非常重要的. 請各位指點.

有對流, 有循環, 當然有其一定的效果, 不過看了很多的造景作品, 水草生長, 都是沒有用底部發熱線的, 出來的效果都非常好呀. 有機會是作者的環境不同, 氣溫是有很大變化的, 底層的溫度會更低, 就可能要用發熱線來活化底層.

找找 "發熱線" 有幾篇有關討論的.

thanks Super, any more comments from others.

缸底發熱線, 營造一個溫暖的泥牀, 有利水草生長, 有下列優點:
1. 使水對流, 將水中養份帶入泥牀,
2. 同時將泥中污物帶出泥牀
3. 溫暖泥牀幫肋植物根部生長
4. 溫暖的泥牀加速生物硝化過程分解成養份, 使泥牀更肥沃.
5. 加長泥牀壽命
6. 抑制藻類生長, 尤其是缸邊與泥面一帶之藻類

我用了效果很好!

參考下列網頁 :

http://aquaticconcepts.thekrib.com/Articles/PAM_Substrate.htm (此文比較 沒有發熱線, 有發熱線及用隔屎板之實驗)

thanks a lot

tcc: how about summer, when temp is high? heating is not needed during those time, what do u do with the substrate heating then?

To Allan 2002:
I hope TCC won't mind I answer this question.

Of course, keep turn on the substrates heater plus the water cooling system!
Will you turn off your aquarium lighting during summer time, because it will heat up the water?
Will substrates heater gives a benifit to the aquatic plants?
In my opinion, we should try ourselves and make a comparision before give those straght forward comments.


Regards,

看了 tcc 介紹一文, 點出了用底部發熱線的好處, 對長期維持底層活化和草缸的穩定, 有一定的用處, 但是先決條件, 都是要在一個溫差較明顯的水溫下, 底層的對流才能形成. 在香港如果不用水冷機, 可能真的要在冬天時才可啟動發熱線了.

SuperCTW comment is what i have in mind. In some places, even summer temp is only up to 25C (ave ~21-22C), then heating is sensible.

If one is willing to invest a lot in those high tech equipments+electricity, then not a problem. U can have substrate heating+water cooling during summer.
But I guess not many people will want to get a water cooling system bec of wanting to operate the substrate heating during summer.

Light is a diff story, if u want plants, light is a must.

Substrate heating cable runs pretty high in price by the way. As most of you said, the benefit is there only when it is turned on (in winter mostly). I did some research for it in the past, but the price is just oo high for me to justify.

How much does it cost to wire a ~34" tank in HK Including the temperature control.

BTW, is anyone using the ADA Substrate heating board

34" can use 25W cable. It cost about HKD 260 (RENA) without temperature control. The temperature control will be another couple of hundred.

夏天 + HQI + 缸底發熱線 = 慢火水草煲魚湯, 上下前後左右夾攻, 唔錯o架!! 好正氣o架!! 好甜o架!!

無水冷係唔掂, 所以我成日話, 濕頭由水冷開始, 真係肺腑之言, 語重深長呀!!

言歸正傳, 缸底發熱線相對於水冷, 並不算貴 (你買ada發熱板就另計), Rena 25W 約$250, 24-32吋缸用, Hydor 有調溫, 約$300, 如果你買rena, 記得另外買多幾個吸盤, 因為包裝內只得2-3個, 唔夠用, (有乜理由個圖示範都有10個8個啦, packing 得2-3個), 我覺得hydor牌子產品較佳, 不過買左無法子啦!

今日特登度下溫度, 水溫26度, 泥牀30度, 暫時不須用暖管, 水冷晚間亦沒有啟動, 水中由左至右水溫一致.

用了缸底發熱線, 最明顯是泥面一帶玻璃面的青苔大大減少, 縱有少量亦很易清理, 部份水草之根部生長理想, 如香姑草在泥裡的根比在水中的根要密要長很多.

拔草時, 縱使水草根已長得很長, 心想一定抓得很實了, 誰知不是呢, 稍稍用力便可將水草連長長的根拔起了! 因為泥牀被熱流帶動, 鬆鬆的, 可有空間讓根伸展呢! 不用蚯蚓了!! 熱流向上也不讓藻類那麼容易附緊缸面了.

如果有夠力的水冷系統, 真可以試用缸底發熱線, 效果真是不錯的呢!

TCC:

Several questions:
1) How long will you turn on the substrate heater for a day?

2) How to control the on/off of the heater? (Manually or Timer or Temp. Control?)

3) If ignore the HQI and other heater(s), what is the water temperture and the gravel temperture in your 24" tank?

4) Do you find yourself will use less liquid fertilizers for the aquatic plants due to the good circulation of nutrients from the substrates?

5) What is the branch name and model no. of your substrate heating system and its specifications?

6) What is the price different of your electricity bill after installed the substrates heater?

7) Do you find the fishes or other organisms behavior acting different after installed the substrates heater?


Thanks for sharing your experience in using of the undergravel substrates heating system. I definitely will try it in the future! There is really a lot of think to learn and experience in the tropical fish hobby.
