MurpReefer Posted January 27, 2020 Share Posted January 27, 2020 Hello, I purchased some live rock from a guy who was tearing down his tank. It had been up for ten years, I thought it might be a great way to get more mature bacteria. Currently live rock is in a home depot bucket. I see the tan sponges are good, but what are these black half dome looking flora or fauna? Quote Link to comment
