Actually, I am a new hand here as well, may be I can share some of my experience with you: (Sorry I can't type Chinese in office)
- [18"x12"x12" ]
My tank is approx. same size as your. Mine is 18x13x12
- [AA掛燈兩支光管,10W一支,是NEC三波長形白色光管]
I think probably your light is not enough, your tank capacity is ~42L water, according to the high hand mentioned before, at least 1W of light for 1L of water. My tank capacity is ~46L and I am using a total of 47W PL light (But I think mine should be just bare enought)
- [掛缸過濾器連接隔屎板]
For the grass tank,隔屎板接過濾器 is not suitable here because it will disturb the grow of the grass root and the 根肥will be sucked by the 過濾器 through 隔屎板 as well. For me, I am just using 掛缸過濾器 and 潛水過濾器.
- [過濾器內用了生物環及黑色炭棉及白色普通棉,另加草泥丸在濾器內]
If your water is clear already, 黑色炭棉 may not be used because I heard 炭 will absorb the 肥. For me I am using 生物環,生化棉.
- ]有用CO2每次換水也有加甘露肥及AZOO(水草主食液肥)]
For me I will add 硝化菌 every week as well to maintain a stable 硝化系統. For the 液肥, I will suggest you to add it everyday (of course the portion should be 1/7 of the weekly portion), because if you add too much 液肥 once a week, it will easily cause 藻類 problem.
Also, pls check you PH value as well, most of the grass like 微酸; also if the water temp is too high (>30 degree) grass will easily get die as well (I am using a small computer fan to keep the water temp to ~29 degree at max)
I think there is a lots of high hand here who can answer your question in more details...Mine is just a little little experience
