水草情迷

the plant usually has bubbles. but, no more bubbles these days. The system is the same as before. when I change the water, bubbles come out again (surely from the plants and not oxygen). The only thing I can think of is the tempature changed.

my plants color changed to transparence and melting.

18" L x 10" H x 12" W
T8-15Wx2
have co2
eheim 2215
temp. 27 degree (with fans already)

Can some body confirm if the plant will get melt and die when the temp. is 27-28 degree?

The lighting is not enough. 15W x 3 will be better with 6500K. Try your best to keep the temp not higher than 25 degree. Let's check my tank info. below and my plants got a lot of bubbles.

Elachan,
thanks. I did some testing yesterday. I was wondering why there are alot of bubbles everytime after I changed the water. I have changed the water yesterday again and make sure that there are no bubbles on the plant. Then, I turn on the light and co2. There are million of bubbles again. So, I believed that the 含氧量 is too low.
Now, I have add air pump during lightering and co2 is off. see whether it is okay in the next few days.
by the way, 含氧量 is low because I have too many fishes? If not, what made the 含氧量 low in my case?
i have the total of 11 短鲷 & 6 shrimps in my tank.

that is the tank size. after the soil layer and leave some space at the top of the tank so the water wouldn't come out, then the water volume should be less than that.
as I remember, there should be about 26L of water. So, I have turn on 2 tube only.
my lightering is T8 15wx4 tube. since 1L require 1W of light, so I have only turn on 2 tubes.

Should I turn on 2 tube or 3 tube in this case?

我14"缸 高約9"水 Dazs PL36w
26度

開燈+co2 1.5/s 約4水時就有波波升上去（矮珍珠），滿泡（迷你6角苔）

水中夠適當co2+光線就做到光合。

MY LIGHTERING IS T8 15WX4. EVEN I TURN ON CO2 TO 3 BUBBLE/SEC AND WITH 60W LIGHT. THE BUBBLE ISN'T MUCH. HOWEVER, WHEN I CHANGE WATER, THERE ARE MILLION OF BUBBLE COME OUT FROM THE PLATE. I AM SURE NOT OXYGEN BY FILLING THE WATER BECAUSE I AM SURE THERE ARE NO BUBBLES AFTER FILL UP THE WATER. SO, I AM WONDERING IF IT IS DUE TO THE 含氧量 IS TOO LOW.

octoct,

i should have enough co2, as I am putting about 2 bubble for my tank.
Just check the water, there should be 24L of later instead. So, T8-15Wx2 should be enough to cover the whole tank.
having air pump for the whole night in order to increase the 含氧量, but still not workable today.
all i can think of the difference of the new water vs old water is water tempature beside 含氧量. Now, my tank is 26.5 degree with fan. I am using another big fan in front of the tank and with air conditioner on, let see if it can make the water temp down abit and see the result.

你果d係咩草？同埋你個細缸養左幾多生物？

因為如果太多生物，食得多呵得多都會好影響你d水質。

你係d草如果溶或者變色，即代表水質有d野發生左，草本身有事又點會做到光合呢？

你可否貼下 ph 同埋 n氏3契弟睇睇？



ps: 有高手們可請教關於含氧量嗎？因小弟認為不關這個point。

octoct,

I appreciate so much for your help. I am posting the pictures of my tank attached.
I don't know if I have too much 生物. maybe you can give me some advice.
plants are getting yellow. the front plant leave doesn't open while co2 and lightering is on.

短鯛 : 7條
大和蝦 : 4只
英桃蝦 : 2只

the leaves do not go upwards when lightering is on. what is the problems exactly? I am turning on 4 tubes with 60W into a 24L of water now. The leaves are still facing downwards.
I made the exact measures of my tank now attached.
the tubes are ada tubes.

60W for a 24L tank? That's way too much. I suspect it's the high temperature that make your plants don't grow.

fish fan,
26.5 degree still not make the plants make bubbles and grow well?
should I make two tube or three tube now? 15w each

leoo11: In case I have misled you - 26.5c is good for plants. What I'm afraid of is that 26.5c is the best temperature of your tank. Probably, you take the measure in the evening. If that's the case, it means most of the time (in particular in the afternoon) the temperature will be much higher that kills your plants.

For the lighting, you may start with 2 tubes, i.e. 30W and see how the plants grow. Anyway, I'd say 45W is on the high side.

thank you, fishfan.
all problem solved. my plants have bubbles now. I was doing testing on water temp, volume of co2, etc. however, all these issue is not the problem.
the only problem occured must be 含氧量. I move 8 fishes to other tank and everything is fine now. I have cut off the yellow leaves and waiting to grow with 2 tubes now.

by the way, what is the water temp. that you set for the chiller? 24 or 25 degree?

响另一個post 我提過含氧量呢樣野，可能就咁俾你誤會左係高手，其實我唔係高手，不過係老手，年紀大，想唔認老都唔得。

之前對樓主個缸的情況所知甚少，一味靠估。所以將諗到的可能性都提出黎。
事關草缸的氣泡係光合作用產生的氧氣較多，溶唔晒入水，所以積到咁上下就浮上面，如果D草唔係太茂盛，或者光合作用唔係太旺盛，D氧氣啱啱出就己經溶晒入水。但係新水一般含氧較多，新生的氧氣就容易累積。

不過，睇番樓主 post D 相，D草似乎生得唔係咁好，所以我都同意你既睇法，唔關呢個 point 事。

不過，最吊詭係呢個缸的光夠，溫度啱，但係都生得唔好，真係值得研究。有無人知隻草個學名，想搵下係唔係鹼性水草。
