So What kind of lighting do I need? I'm thinking of setting up a 45g tank. With just regular flouresents. Can I just use 6500K from like home depot? That's what I use on my refugium and my macro grow good. Also do I need to add any supplements, for the plants? I have read a little about the Co2 systems, but I don't want to go that far right now anyway, maybe down the road. Can regular playsand from the hardware store be used as substrate, or do the plants require some sort of nutrients from the substrate? Thanks guy for all your input.
