Thanks for all the responses. I do appreciate it. I'm attaching a more close up photo of a section of it. It is hard. It's got an interesting shape I haven't seen before in algae.

Thank you all. I sent ERC an email asking for help. I'm sure the wife will croak if I go visit. You can't go somewhere and not buy something

Origami, No not flat. It's almost like coral as it builds higher and higher like a rock so to speak.

I have noticed that there is some new algae in my tank. It's hard and almost looks like coral that is green but it isn't. The only thing that has changed is that the tank now gets a lot more sunlight for a longer period of time. Neither my Hippo or emerald crabs eat it. It's every where. When I tried to get some off the live rock I noticed it was hard and broke off in chunks. No one knows what it is so I'm looking for help here. I do use tap water for my water changes. It is what it is and what I can afford. Hopefully some one here knows what it is and how to get rid of it. Many thanks in advance. Oh and it isn't bubble algae.

Hello All, I am a new member here. I have had my current reef tank for around eight years now. It has had some ups and downs. Due to an injury I had to start it over again. It's a 46 gallon bow front with about 65 pounds of live rock. I do have a refugium. I have two clowns, a hippo, two yellow tail damsels and an orchid dotty back who doesn't earn his keep. I have a coral banded shrimp, hermits and emerald crabs as well as a starfish I have had for about four years now. I probably know just enough to get myself in trouble and have less money than I believe to do things with according to my wife. Anyways I look forward to learning more.
