水草情迷

以下這個方法是節錄自 tw.bbs.rec.aquarium.
有人使用這個方法可以將二尺(60公分)的水草缸降溫至26度.有興趣的
人可以試試看. 打算這個禮拜來試試看說.

材料：１．保麗龍盒
　　　２．水管一條
方法：１．將保麗盒上打二個洞
　　　２．把水管的二端分別插入那二個洞，作為出水口及入水口
３．在保麗龍盒內放滿冰塊，並把保麗龍盒蓋起來
４．將入水口接在陳水馬達上，出水口放在魚缸內

恕我直言, 咁做法完全係冇用ga, 因為冰塊好快就會溶, 而且令到d水溫快上快落, 魚好容易生白點。同時個盒因為水壓問題, 好容易漏水, 如果密封咁你下次又點添加d冰呢?

I agree with PPHK. The ice will melt for sure so this method is not for a long term use. Unless you are prepared to change the ice every half hour 24 hours a day, I don't think this method is workable.

漏水就應該唔會, 佢應該係用個盒載住o的冰, 然後去 "冷卻" 條水管. 再"冷卻"流過o既 水, 不過膠水管的導熱性就很差, 驚o的冰溶晒都唔降得幾多度呀.
如果真係要用冰, 不如雪幾支膠樽冰, 直接放落缸可以重冇咁麻煩.

便宜之選, 都是用風扇喔.

有dry ice 得唔得?
溶o左可以有o的co2種草bor!!
(純係小弟奇想)

I tried with dry ice before. About a year ago, I bought a box of icecream from a Hong Kong food distributor, they packed the icecream with dry ice. I was also curious and put a handful of dry ice into my tank. The dry ice bubble like mad and about fifteen minutes later most of my fishes become inconscious (I guess they suffocated) and sink to the bottom of the tank. The water temp was not drop much about 2 deg. I immediately change 50% of the water and about 60% of the fishes recovered, but 40% of them RIP (rest in peace).
Dry ice is more difficult to control.
