Given all other factors being equal, do you prefer an internal overflow or an external overflow and why?
Adding in the mention that innovative marine uses a coast to coast overflow which I really like, and I have an internal IM 50g tank already. ..... but I also like the aspect that the external overflow tanks use a split return plumbing that they have separated to opposite sides of the tank.
I'm leaning more towards the internal version again for several reasons but I'm curious to hear others thoughts.
