I have ALWAYS hated my rockscape in my tank! Since my funding is low right now I am going to construct some DIY rock using white portland cement and oyster shell. I have access to a creek so I estimate a 2-3 week curing time. Now I just need to come up with some cool ass shapes to make the tank look better. I was going to purchase the cement today and get started but the store i am buying from is closed today out: . When I get it started I will post pics of the rock molds and the general re design before and after.
