水草情迷

I'm new and don't know much about how to set up a balanced tank !! My questions are:

1) 掛濾 or 濾桶, which is better?
2) I Intend to set up a tank of about 20"x20"x13" for tropical fishes plus "water grass", pls advices (in details) what types of equipments I need to buy/set?
3) In general, any information/books/forums to assist me to set up a "balanced" tank for my fishes and grass ??

Thks in advance !

For Q1, 濾筒is much better because the place for inserting filter materials is larger
For Q2,u should have co2 system (no matter diy or buy outside)for the water glass. A bright light depends on the type of your chosen water glass. It is better to keep constant about the water temperature for the glass (under 30degree)

Actually i am also new here for around 2months, u should better to come here and read more articles from other brothers so u can equip more knowledge in this aspect.
