So, I am planning a new build somewhere in the 125g-150g range. I am new to saltwater, so I don't have much experience with sumps. I have a freshwater system for zebrafish housing that has overflows and a sump, but that all came as one unit, so I have never built a system piece by piece.
Here's my question: If you were starting from scratch, would you rather have a tank with built in overflows, or would you use a HOB
overflow box? What are the pros and cons of either set up? Your opinions are appreciated....
