水草情迷

48"草缸, 未有水冷, 昨晚水溫升到30', 今朝一早起身, 一堆櫻桃蝦/藍蝦屍體, 大大細細都有!
估計草叢內仲有屍體, 水體已經起泡, 即刻要換一半水.

嘩..
你住邊頭呀師兄..
咁熱@@?

You have to install a chiller for shrimp tanks. Shrimps are sensitive to temperature. I don't know much about shrimps but in my experience, you'd better keep the temperature at 25c.

我個缸都30度
而家冇開冷氣都29度...

樓主都係買返個水冷好d
如果唔係就唔好養蝦, 蝦仔好難過30度

尋晚都30度? 樓主屋企開好多電器? 空氣唔流通?
定係用左好熱既燈?

嘩再過一排再熱d仲得了?
咁大個缸風扇都唔掂，係時候入水冷la

看来都系要24小时风扇吹吹了

如果唔想買, 可以試下diy
用usb 火牛 + usb 轉電腦風扇3pin + 電腦風扇
自己諗方法fix 到就得

好處: 平, 材料可能已經有唔洗點另外買

壞處: 效果平平, 因為如果天氣真係好熱, 30c 風吹落30c 水, 唔會有好大效果, 而且usb 供電只得5v, 風扇唔係全速

經過兩日死蝦, 換水, 同觀察, 發現朝早有個共通點, D魚和蝦在早上都浮上水面呼吸, 更有蝦跳缸!!!
明顯係缺氧...
估計密植水草, 晚間光合作用停止, 水草反而吸氧, 呼CO2, 水中含氧量下降, 再加上最近氣溫高, 令水中含氧量更低, 所以, 生物會缺氧而死!!
反觀在開燈, 同時開CO2, 水草進行光合作用而放出氧氣, 魚/蝦都很自然, 無特別反應 開燈時水溫仲高(比深夜時), 如果係高溫引至死蝦, 應該開燈時會觀察到蝦有異樣.
所以, 昨晚熄燈後開氣泵, 再觀察多兩日, 睇吓有無估計錯誤.

缺唔缺氧都好, 溫度始終係一個問題
趁依家未到最熱就準備好呀碼

又或者減小D草和魚蝦啦！

溫度好重要 未入夏就30度水 到7 8月時點算 頂得一時頂唔到7 8 月喎 不過水冷真係幾貴 試下風扇
我個缸上星期都28/29 度 得一把風扇 有死蝦 星期日拿拿聲出魚街買左把6頭扇 水溫即刻降到25度 晚上更試過24度
手放入水真係feel到d水係凍ga 風扇仲有位可以再吹低d 而家睇下頂唔頂到6 7 月

星期日整好左, 經過幾日觀察, 比室溫低兩度. 我個係48"缸.
都算安靜, 風力大, 24小時開, 燈摸上手唔熱, 同之前差得遠. 3日水位降約1.5cm, 可接受.

uiwanted: "D魚和蝦在早上都浮上水面呼吸" - Just one more point to consider: the higher the temperature, the lower of O2/ CO2 dissolving rate in water. That may be also one of the reasons why fishes 浮頭. BTW, have you added any chemicals to your tank?

Fish Fan,
I added CIDEX (buy from China, it's so cheap) for the CO2 supplement for half year. But I got CO2 cylinder already. The CO2 setting had not changed so far but maybe the temperature cause the O2 dissolving rate drop. I also consider your point. Therefore, I applied an air pump when the light and CO2 off.
