I wanted to post these pictures because when I was posting growth pics in another thread earlier this month, I noticed something else. If you look at the first picture on the rocks, you will see coralline along with a red velvety algae. I installed my ATS shortly after the first picture and in the second picture you can see what an impact it had on that red algae. The rocks are now just corraline and white where the other algae was. I thought it was a pretty good indicator of how well the ATS worked.
