水草情迷

My tank: 16" long X 10.5" high X 12" wide = 33L of water
Lamps: one NEC 10W 'sam bor cheung' tube
one 4-tube style 27W 'Sanki' PL tube lamp
CO2: one DIY CO2 (bamboo chopstick as outlet) + one 'chit chit sik' CO2
Lamp on time: 1400 - 2200 hours
Fertiliser: Tetra Floride a few drops daily
Dupla Plant 24 1 drop daily
Water current: slow
Plants: siu shui yung, RICCIA, golden fish grass
Problem: NO BUBBLE AT ALL!!!!!
Please help me!

是突然不出泡還是從未出過泡？有些水草是不易有氣泡出的。另外，如果細化器(竹筷子)距水面太近，有時會降低溶解效率，可能也是原因吧，我遇到過這種情況，後來索性放到缸底部，但因為增加了水壓，co2釋放比放置在近水面處時弱些。

bubble never appears and I mean RICCIA
bamboo chopstick is just above the sand
so, I have no idea why.....

會不會是過濾器的問題？你用哪種？

你的情況有幾個可能:
1. 唔夠光--你可以試下將d鹿角苔放到近水面一些, 如果之後有泡出就即係話你要加多支燈囉~~
2. 水流--你可以試下索性將過濾器關一會兒, 如果開始有泡出就即係水流太強la~
3. 剛剛轉換燈管, 水草需時適應, 呢個情況就乜都唔駛做, 等.
而家好難斷定係邊種情況, 你要慢慢試下, 唔好放棄呀~~

如果不是過濾器的問題，都很有可能是光照的原因。我的缸是20吋，高度約12吋，用三枝15WNEC三波長超光管，莫絲和鹿角苔均出泡很勁。供參考。

Tomy:
為何你用兩種CO2（DIY CO2及用完即棄的唧唧筒CO2）？

1. 我用eheim最小那種沈水式過濾器。(好似2013或2003)
2. 照計不是我用一支27W PL管 加一支10wNEC白光管光過三支15W NEC光管嗎？(我指流明量。)
3. 唧唧式未用完唔好

Hi Tomy,

Have you check the KH level of your tank's water? I've learned that if the KH level in the water is too low no matter how much CO2 you pump into the water there is just not much CO2 dissolved into the water. Hence no photosynthesis can be carried out by the plants.

Hope this help.

thanks
I have checked the KH and it is 2-3. I know it maybe too low. Let me buy some soda powder.
And, turing off the filter, raising up the RICCIA to the water surface....
I will try everything, I will try my best, I will......

Tomy，
你的草出泡沒有呀？提高了KH之後的情況點？我都想知多D。

退出。

我覺得Sang說的好對。PL雖然好光，但有些未必是三波長，其實水草對光譜的要求可能多過光度，因曾見不少草友的缸，不是很光，但泡就出的很勁。

請問你講的24"FL NEC 管是指電器店的普通光管或是在魚街的營光管呢?

二月三日
加了一茶羹梳打粉，KH上升至7。PH也上升(我估大過8，因去到試紙最藍色
