Refugium or skimmer upgrade?

Thanks - yeah I think I'm leaning towards the refugium, but I'm still thinking about it... A system with a nice skimmer and a bare sump seems more "clean".

Yep, it all depends what you like/want. Both systems can work well. Using both is of course even better if you can do it, but you need the space obviously.
