Im starting my third tank, a standard 10 gallon 20" long. So far I have a large piece of Mopani driftwood, and I ordered a bag of Flourite Black Sand that should be here Wednesday. My camera is MIA right now so I cant take any pics. I have a couple questions: -Will one 15.4 pound bag of sand be enough? I want it to slope steeply in the back left where the driftwood will be. -How many watts of lighting should I aim for? I want the tank to be heavily planted and I plan to plumb my CO2 from my 30 gallon into this tank. Im hoping to stock it with hc for a carpet, some stems along the back, and some christmas or flame moss, and maybe some anubias petite for the driftwood. For fauna I want a small school of guppies or tetras, and some CRS or Amanos.
