Hey I have a question. I’m new to saltwater aquariums, and have decided to set up a reef tank. I have a few things in the tank and have been up and going for about five months now. I’m aware that I need new flow for my tank, but can anybody help me identify this type of algae growing on my Sandbed/Subtrate. And what I can do to correct it. Just looking for a community to help me learn and grow in this new hobby.
