Ok so I have had this tank for three months and this is what I have come up with. I am using one 48" t12 6500k and four 40 watt cfls. My co2 is at a constant 30ppm and I am dosing EI and I have a ton of plants going in from my other tanks when I can find time. But let me know what you think about placement. I'm afraid when this takes off I am gonna be overwhelmed with all the trimming once I get my background stuff in.
