Your tank looks great. I really dig the photography too.

You have significantly more coralline growth than me.

How long did you have your tank running until you started to see significant coralline growth on the back bulkhead?

Also, what are your nitrate levels like?

I'm just starting to see some small patches of purple on my back bulkhead. My tank is over 18 months old. Up until about a month ago I think I was just running my tank way too clean.
