水草情迷

種草種了很久，草的表面有很多青台。放入缸的魚仔，有米其﹑飛孤及燈魚等，但養了不久後其尾部開始不段變幼，最後死亡。最近已約２天換水。
但小精靈﹑大和蝦又冇事。原因如何呢，請高人指點。 又濾水 “FLUVAL 205” 是否合養草，因其水管是接琴式管。

Just a few suggestion for your consideration:
1. "草的表面有很多青台" - That's normal. They appear on the glass, too. That's why you have to clean your tank regularly.
2. "其尾部開始不段變幼" - I suspect that is a kind of infection. You have to address this. Other creatures don't die doesn't mean the water conidtion is ok. If you find the death of fishes consistent, you may consider medical treatment. However, that will kill those shrimps, fishes and even plants. Take this as the last resort of action. Like you said, keeping changing water will help.
3. As what I read from the Hagen's website, Fluval 205 should be fine. "接琴式管" is not a factor for consideration. BTW, how large is your tank? 'cos 205 only has a flowrate of 420l/h. It may only be suitable for a 12"/14" tank. If you use it for a 24" tank, that may be the reason why germs exist since the water is not in good circulation.
4. What about the growth of plants? Are they in good condition? Give us some more info of your tank setup, including size, equipment and daily maintenance. That helps the diagnosis.

你唔好太無心機啦
只是青苔,我生黑毛都己完成消滅.青苔同黑毛相比只是小兒科.
所以你一定要努力,唔好太易放氣.
現在草缸生長得非常好.到是在加相啦.
你d魚肯定受細菌影響.有d茵唔係話落藥就可以.
所以下次買魚要小心d,養好左就唔好得閒無事就加新魚.

You can find Excel in any shop in MS. For the dosage, you may find the extract below from Excel's official site:
"On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 gallons*). Thereafter use 1 capful for every 200 L (50 gallons*) daily or every other day. Dosing may be slowly increased in high-growth aquariums. For smaller dosing please note that each cap thread is approximately 1 mL."

Hope this helps.
