Refugium or skimmer upgrade?

[TheReefGeek]

For 75 gallons, the Berlin Skimmer should be good enough, once it is tweaked correctly, it should not require constant tuning, only if you change your water level or put in addatives and such.

But, an ASM or Euro would be better of course.

I would stick with the Berlin, and add a fuge, this is just personal preference.

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.
