Okay guys, I've built a 100 gallon freshwater aquarium. Now I've got an empty 20 gallon that I want to use for a nano starter reef tank. I've done a lot of research in the past couple months. The only thing I'm having difficulty I'm deciding about is a filtration system. I'm thinking about going with the LR
and skimmer. What kind of skimmer should I use? What kind do you guys use?
