水草情迷

溫度計,有時人係房頂到既都唔想開冷氣啦,開左又凍得滯(我開到最細都見凍),感覺又唔環保又哂錢又虐待自己,我通常都係訓覺先開~

風扇吹魚缸唔吹水面有冇降溫效果? No. cooling effect is due to water become vapour...
There is an excellent (and interesting) debate before about the theory of cooling by fan... Let me search... get back to you later.

風扇吹水面降溫效果 => My 24" tank. drop 2 deg C max. at Aug last year depends on humidity - still works around 85-90%.

No effective at 99% humidity.

理論是可行的：
因為風能夠促進蒸發作用，水汽中的潛熱會隨潛發而被帶走
缸表面溫度下降，間接令水面溫度下降，然後基於缸底的水較熱，缸底的熱能會慢慢擴展上去，再被蒸發，因而達致降效果。

小弟愚見，但很多事物不能只用理論解決的。

睇睇高手嘅經典討論啦

得益不淺，原來我地既草友咁有科學精神

Thx! this is exactly I like to search... really a classic discussion.

Note one more thing - they discuss and debate really hot ...but they do this with respectful manner. That is the most admiring part.

真係養得魚耐既人耐性都會高d,待人接物方面都溫柔d~

睇完哂,完全覺得佢地研究緊<阿媽係女人>呢D咁哲學性既問題一樣
