Where do you live? What local indigenous rocks are available in your area? I never considered the basalt rock local to me to be very pretty (because it is everywhere you look around here) but when I built my 180g tank with it I am VERY pleased with how it turned out! Because I had so many different rocks to choose from I could be selective and fit the pieces of rock together how I liked them. If I had paid for rock I would have had a much smaller selection to choose from and I would have wanted to use every last piece I paid for. Look around and see what you can pick up for free before purchasing a bunch, especially from online.I have a 55 gallon tank that I am going to replant and would like to add hardscaping to add dimension. Any suggestions of good places to find quality hardscaping?
