I ran just a refug for about 5 months, and my water params were very good. I added my skimmer, and not much changed. I agree with Tangster saying the skimmer takes out what the refugium left behind. Also, I think it really matters how much bioload you have. At the moment, I am running a very light bioload, so I probably don't really need both a skimmer and refug. I plan on increasing it dramtically very soon, so I'm sure I will benefit greatly from a skimmer and refugium when I do.. One thing is for sure, the pro's of having both outwiegh the con's, bigtime..
