I need some input on adding live rock to a tank so it looks good. I have a 150 tank and I will be aquascaping with 300 pounds of lr tomorrow, any do's or dont's. This is my first time doing this so any input would be put to use. Will 300 pounds fill the tank up pretty good in your oppinion or will their still be a lot of open space? Trying to get a pic in my head on how to do it but I'm clueless here. HELP,,, lol
