I would like to keep this low tech for a while and once I am ready to buy good lighting I will get one and use CO2. But for now I am going really low tech and basic here. I am trying a variety of plants that I have just to see what happens. I had some extra java moss, drarf hair grass, micro sword and riccia so I threw it in there to see what happens. Hopefully I can get some java fern sometime. Not looking to go crazy with plants. I would be happy if I could make something that looks like my 10g.
