I am doing away with my Nuvo 40 AIO that I had my Apex 2016 on. I am rebuilding a 125 gallon at home and will move the Apex there. the 125 has a manifold and will obviously run completely different equipment than when the Apex was on the Nuvo 40. So the question is, when moving from a 40 AIO to a 125 with sump, what would you do with your Apex--reset/start from scratch, or try to reformulate what you already have/rename everything?
