Hi, I am new to this forum and new to planted aquariums. I just set up my 20 gallon tank with the proper filter, heater, flourite substrate, plants and etc. I want to know if the basic bulb that came with my tank cover will be enough for my assortment of Amazon Swords, Banana plants, Crypts, and Anubias? What about fertilizers? Any advice would be appreciated. THanks! ^_^
