I hope to set up a 36 gallon bow tank in the next few weeks. I am going to transfer the fish in my 15 gallon to it, but I want to plant it also. I have seen many beautiful planted tanks, some of them have the substrate completely covered with plants. How do you clean those? doesn't seem like you could vacuum them.
