SPS Reef Tank Upgrade: One Year Later

Its been one year since I upgraded my Red Sea Reefer 450 (~90g) to a Innovative Marine Nuvo 170g EXT. I did a lot of work on the tank over the year, as upgrading a reef using the same rock and coral is not always as straight forward as it seems. Even with all the work, I was able to achieve some amazing SPS and acropora growth. While I would say my tank did overwhelmingly positive, I did have some speed bumps along the way, and currently I am dealing with some slow tissue necrosis (STN) on some of my Acropora after finding a cracked heater.

This video documents how the last year went, along with my future plans!
