Refugium or skimmer upgrade?

[IJC]

I'm currently running a redsea berlin turbo skimmer in the section of my sump where my overflow runs in, the centre section is empty. I'm considering two options: 1. turn the centre section of the sump into a refugium, or; 2. upgrade to a euroreef skimmer, which would need to sit in the centre section due to space constraints.

The berlin skimmer does pull crud out, but it takes a lot of adjusting to keep it producing foam, and I know a euroreef would be much more effective (any opinions on the magnitude of this difference?). On the other hand, I do like the idea and potential benfits of a fuge.

My tank is currently in the break-in stage with only live rock, and a few snails/hermits. I want to optimize the system before I get into building up my livestock.

Any thoughts/opinions would be appreciated. Thanks
