黑鋼沙種草,草不生長?

boxerhong · **發表於 :** 2010-08-01 01:02

種了半年,草不生長,有(牛毛,穀精<<死了,椒草,鹿角皇冠,迷你皇冠,迷你水榕<<不生長,莫絲,鳳尾苔<<生長好慢)
30X18X22"缸
LED 45W大白光
DIY CO2長開
TMG散裝液肥
水硬度140-155PPM
PH 7-7.5
沒有基肥及根肥
水溫: 26-28度

是什麼問題令草草不生長?

1. What is "LED 45W大白光"? Are the bulbs of 6500K? I'm not familiar with LED, let other c hings help.
2. pH is a major problem. I'd say 6.5-6.8 are the most suitable range for plants. What exactly do you have inside the tank? If you have soil, it should be that high.
3. 28c is ok, though it's on the high side.
4. How many bubbles per second for the CO2 supply?

it's is around 10000K

i tried the 欖仁葉,but it change my water very 黃,落活性碳又會吸肥.....落PH DOWN又好快上番.....無辦法><3. 28c is ok, though it's on the high side.

1sec 1 bubbles now

你種那些大多是不用插泥(沙)的，唔關黑鋼沙事，我用黑鋼沙都種左幾年都無事喎

缸仲有火山石
現在用大D樽加大DIY CO2份量,希望有改善

boxerhong:
1. 10000K are not for plants.
2. "鹿角皇冠,迷你皇冠,迷你水榕,莫絲,鳳尾苔" All these are 陰草 and "牛毛,穀精" are 陽草. For 陰草, you should have at least 3 bubbles per sec CO2; for 陽草, you should have at least 6 bubbles per sec. Also, like rubbishwing said, you should not put these 陰草 inside the soil layer.
3. Are you using 黑鋼沙/欖仁葉? "黑鋼沙" should be of neutral pH. Why you choose 欖仁葉?

我只係當初用欖仁葉來ph down,無咩意思。

如果真係燈問題，要換咩燈？因為個缸都有成32x18x22...butget有限，再買貴器材實比內子罵死︿︿

boxerhong:
1. I don't have experience with LED bulbs. I'm not sure if you can just replace the bulbs with 6500K.
2. I don't know what's "欖仁葉". But if the purpose of them is to lower the pH and you now say it's as high as 7-7.5, something must be wrong. Do you have stones/ rocks inside the tank?
3. What's the height of your tank? 18" or 22"? If it is 18", T5HO tubes should be fine. Otherwise, you may need an HQI.

BTW, would you please amend your signature to avoid unnecessary promotion of products.

Good luck.

黑鋼沙本身係無肥架,你種有根插草最少都要加根肥喇.

我都有好多石都無問題，亦係用tmg散庄液肥，之前diy co2，轉用樽一個月，所以同你情況差唔多，真係唔知咩問題喎？
咦！你個缸燈照時間幾耐？

以下係我個缸

這是否正常?
再找不到辦法,要反缸了!! :cry:
