So that why i wanted to know whether if i can use real wood or not then i will use real wood. Also, what is fertilizer or CO2?
Wood purchased from a reputable aquarium/fish store should be OK. The darker wood (used to be called mangrove root) like I have in my tanks (see my photos under "Aquariums") is heavy enough to sink immediately. The lighter buff-coloured wood like Mopani wood will float and has to be weighted down. All wood will leech tannins into the water for a few months, colouring the water a yellowish/brownish tint like tea. It is harmless to fish but some aquarists don't like the look of unclear water, so they boil the wood or soak it for a week in a tub of water to remove some of the tannins. Some stores have wood in their fish tanks and will sell it to you; one advantage is that it is soaked and most of the tannins will already have leeched out. The disadvantage is that it has been in contact with fish and could carry parasites or disease just like buying any fish, so you should "quarantine" the wood in a tank of plain water for a week. This is worth it, because the tannins have leeched out and the wood is heavy enough to sink.
Fertilizers usually refers to liquid fertilizer for plants, that are trace elements and minerals that aquatic plants require to grow. Most of us with planted aquariums add liquid fertilizer once or more a week, depending upon the plant needs.
CO2 is the gas carbon dioxide that we all expel in breathing, and fish do the same when they respirate. Plants need CO2 to grow, and some plants get enough from the fish in the tank, while others require more and some planted tank aquarists buy CO2 units to add CO2 to their aquarium. I've never bothered with this, it is expensive and in my view not necessary unless you want to grow certain plants faster. You can see what my tanks look like without any CO2 except what the fish provide.
