水草情迷

Simon,
I think it is because the lightering was too much. Since the plant didn't grow properly, so i try two tube, 3 tube and 4 tube. AT the end, the wattage will be too much and made the plant burned. Anyway, I will keep watching about the growing and bubbles in the next few days. I believed that all my problems is overbreed fishes. When the plant got some changes, I will post out some pictures with you guys for further discuss. or a lesson from you.
Actually, I have ordered a 4 feet tank and will be delivered around middle of June. so, I can remove the overbreed fishes to the big tank once they are setup.

先恭喜你D草OK番

其實依家依你咁講有2個問題：

1. 光太強 15X3 or 4
2. 魚屎太豐盛

第1個point 好易解決
第2個point 其實唔洗運走d魚：比較好的方法係餵少d + 勤d換水

ps; 等睇4尺缸

yes, i am using 15wx2 now.
I am changing water twice a week and 1/3 water each time.

2. 魚屎太豐盛 << 同草有咩關係 ??

真心一問..

i think it is not 含氧量 again since I have remove all the fishes to other small tank.
in the past week, there is no bubbles when the water temp is 26 degree. Since I have turn on 2 tube (15wx2) only, the plants are going well.
But, the plants are not good these few days because the water temp. has gone up to about 28 degree. the leaves are folding due to the temp.
I think i can only prove whether it is the water temp issue only after middle June, as I will get a chiller for my big tank.
In these few days, there are no bubbles even when I change the water. So, I believed that it is the water temp mostly.

Do you guys agree that or experience anything while water temp is 26 degree?

since I do not have fishes in the tank. So, I changed 80% of water and found that there are bubbles come out from the plants only for the first 15-20 mins.
here is what I measures from the tank with air conditioning on.
temp: 25 degree
NO3: 5 ppm
copper: 0.25 ppm
NH3/NH4: 0 ppm
NO2: 0 ppm
PO3/4: 0 ppm
KH: 2
GH: color very difficult to read. maybe 5.

Can anyone know what is the problem? The plant's leaves are folding. Will post some picture.

just discover that maybe the flow rate of the canister is too large. watch two days more to prove it first.

leoo11: The bubbles coming out after changing water is normal but this is not due to the plants. It's just a physical reaction. You can't count on that phenomenon and claim that the plants are healthy.

what do you suggest me to do to make it more health and better? I try everything already. should i add soda to increase the KH?

leoo11: There is a chance that the water flow is so fast that no air bubbles can be accumulated. For your tank's condition, I would suspect:
1. Too weak (30W) and too strong (60W) lighting. Probably, your plants are dying - replace them all and try again.
2. How long is your light on each day? Are they 6500K tubes?
3. Like I said, temperature is a key for plants to grow. It should not be fluctuating that much. With your air-con on and keep the temperature at 25c, it should be fine. But what is the temperature when it is off? Few plants can survive at 28c. You have to find some ways to keep it lower than 28c.
4. BTW, how long has your tank been set up? When do the plants start withering?

The plants are okay except one. their leaves are folding. I am taking a picture for you to see. I just don't see the plants are breathing with bubbles, and wondering what is the problem only.

they grow, but just try to make it better condition or with bubbles.
oh, didn't have a camera with me today, maybe send you to see on monday.

i am still keep trying

To eliminate the factors of strong water flow, you may turn off the canister for 4-5 mins and see if there are bubbles.

fishfan,
thanks. i have taken some picture for you to see. maybe its easier to understand.
I have turn off the canister awhile and no bubbles. it looks to me that the plants are not breathing but they grow. Some leaves are going downwards. (see pictures)
