I need some major help.. About a month a go I notice that I started having problems with my tank. Last week I did a partial water change to try and help it but now it's worse. My live rock has now turned completely black. The water has a greenish color to it. I'm not quite sure what I should do. Do I have to have live rock? I only have fish in my tank. My tank is 40g, and I only have 4 fish. I've wanted to expand but now I just want to keep it simple.
