水草情迷

so effective at cooling because of the large amount of energy required to convert water into a gas.
Pros:
- very cheap
- efficiency, cooling water 5 - 10c
Cons:
- a little bit large but you can make it smaller
- evaporative too fast, you may need fill water into little tank
p.s: put it in the tank and connet the tube to the filter
bigger is much effciency

what's the difference by simply blow directly onto water surface ?

I think this is better..........since the 花洒 create much larger surface area...........however, this method will make the surrounding air very wet......

我諗下面個泵可以唔用，放高d等d水自己流番落缸。相反，上面個入水花洒前面可能要加壓，否則d水唔夠力噴出來。
呢個設計可能唔係好適合草缸，d 二氧化碳好易走晒。
