[ATTACH=full]24337[/ATTACH] Hello everybody!\n\nSo I bought a new 75 Gallon tank that's in the planning and refinishing phase. I have a question. I've attached a picture. I'm wanting to build a rock pillar. I have about 50-70lbs of dry rock to work with.\n\nWhen we set up the 75gallon we are basically moving everything from the 46 over we are reusing the current live rock and water.
