I'm liking the scape. Are the rocks completely against the back glass?
Thank you. The majority is actual old school live rock. I didn’t have a plan, I just put it all in and was happy with my first attempt. Initially none of the rock touched the glass at the back, it’s mostly a few millimetres away to maximise space but as I added more coral I realised I was running out of suitable places to put it so I ended up bulking up the top with some caribsea life rock which does touch the glass at the top and a few bits that ended up lower down the back. I can pretty much see from one end to the other down the back though.
