FWIW if you're having algae issues, your 7 inverts simply won't be enough. I did a BB in my BioCube14, I liked it. It looked so sleek and modern. However I noticed right away my Pods, micro brittle stars, and bristle worms immediately took a huge hit. These guys will all help with turning the sand bed over and reducing detritus thus reducing algae. I would imagine if you removed them too you'd see even more of it on the rocks or bottom glass. You'll see many tanks have immaculate sand. It's always achievable. I had my immaculate black/white sand (hated this stuff it showed everything) after a few months.
