So I am finally, actually being able to set up my new tank now! I decided to use some larger river-type rocks as a substrate although I don't think I will cover the entire bottom. I found out that my mom had just what i was looking for in her backyard!
So, other than cleaning them really well and making sure that there are no sharp edges, is there anything else to do to make sure they are safe for the tank? Are all rocks basicallt safe if they are clean and smooth? Thank you!
