Wow those are some beautiful pictures! Great setup. The rockscape and coral placement is really well done.I'm out of town on a business trip but wanted to update this..
Before I left, I had been fighting off a Cyano outbreak, while trying to get my nutrients balanced. I'm hoping to avoid using Chemiclean for now because this tank is sumpless and my skimmer is a HOB. I'd have to take it offline and get an air pump if I went that route. Treating it like a learning experience in trying to get things under control without what I call a "shortcut" like Chemiclean.
Anyway, here are a few coral shots. (edit: I'm not sure why but the R2R image link seems to have changed the pics sideways, even though they're not in google drive)
