120gal mixed predatory reef tank

Growing out frags in the sump provides me with more space than the 50gal. More space equals more frags. Also, because its in the sump there is no glass or fishing line to clean. While suspending frags has some advantages, the fishing line was an algae magnet requiring constant tedious cleaning because no herbivorous invertebrates could service it. I also expect that downsizing to less system volume will improve the skimmer's performance as there is now less water to process.
