Hey guys I've been lurking around reading for a couple years now, never really posted or contributed too much. Just been soaking up all the info I can. I have just set up a new tank its 36"x12"x16" and I have about 2.5" of pool filter sand as a substrate. I have 2 13watt CFL's and an 18watt T8 for a total of 44watts of light. I'm running a few HOB filters for roughly 400gph of filtration and I haven't stocked it with any fish yet. I would like to do a community tank, and I am looking to plant some low-maintenance plants. I wouldn't mind dosing ferts or putting in root tabs of some sort but I don't want to mess with CO2. I would still like it to look fresh and green though, is this possible? Do I need to add anything to the substrate? What do you guys recommend?
