水草情迷

今日做了一個考驗!!!!!!!!!!!!!!!!!!!!!!!!!

1000開始開魚江燈............加ＣＯ２...1 ball/sec.
到了晚上2200回來.....我見到所有魚在上面呼吸...........
光合作用做到有水珠.......係勁多水珠........但點解會在這樣事情發生.
我有50條新燈........加絲帶20-30條..........飛狐本來６條
今日都死了２條......

之從馬上加回氣pump............過了1hr後D魚起死回生

我養了莫絲......大陽草２同４代....加紅色水草........
同時我又發現開大果部filter出水時又會出少Ｄ水珠.......
又加果開慢Ｄ出水時又會勁多水珠

你地有無此現象呢...................

同時又問大家??????????????
大家是不是用桶型filter?????????
大家的濾材是什麼?????????????

請大家出力回答我啦.............
新仔一名..............多謝各位高手!!!!!!!!!!!!!!!!!!!!!

你的缸有大, 都差不多有七, 八十條魚喎..
浮頭是缺氧呀..
那些不是水珠啦, 本身在水裡, 那來水珠
水流慢時, 氧氣散失較慢, 而且聚合較易, 所以會多些氧氣泡呀.
我是用兩個桶的, 只用生化綿, 生化環同白綿.

我的水族相簿

i am using diy co2 in both of my 2.5g(10L) and my 29g tank, the 2.5g i will turn on my handon the back futiler when i turn off my light. it has been this about 4 month already i don't have any problem. i have 4 shirmps and 5 evry little fish in my 2.5g tank.

簡單來說光合作用都要考慮魚的數量問題,不要只想有氣泡出現而強加co2,這反而會令缸內缺氧,尤其你的缸有這麼多魚,要慢慢地調節co2,出現缺氧情況之後再蹤一減少co2.

I've read a book mentioned something about O2 and CO2 in water. The book mentioned that O2 in water will get equilibrium much more faster than CO2. This means excess CO2 will stay longer in the water. The book also pointed out in such case, fish usually died because of the high CO2 level which is not caused by the lack of O2.

Put this in your case. Grass got bubbles mean excess O2 in water. So, I guess your fishes died because of excess CO2.

Just my .02

我認為是缸中的co2含量太高,比魚體內的co2含量還要高,所以co2從高濃度的地方(水)進入低濃度的地方(魚體).時間長了魚就會中CO2毒.
魚停留在水面是因為水面的co2較少,所以魚還可以正常呼吸
注意整個過程和氧氣多少沒有關係,所以不要認為氧氣充足魚
就一定安全!
