green algae on live rock

[Bob I]

So here is what I do. I live in Calgary, and would not use RO/DI if you gave it to me. I do not test for things, do not add anything. I have Coraline Algae growing everywhere. I find it pestiferous at times. I have used different lighting, and found it does well under any light I have tried. Look at the pictures of my tank here web page
