I am going to my lfs in the next couple of days I have a 25 gallon tank, I have a big rock that is about 10 lbs on the right hand side. It really isnt much its just a big piece that is almost square shaped, and I also have little pieces of rock on the other side, but if you add up the little pieces its only 1.5 lbs I think. When I do go to the lfs, should I get about 10 lbs more? Also in your opinions do you all think I should get small little rocks, so I can set it up the way I want? I will post of my whole tank in a second.
