I recently purchased a 20L during the $1/gal sale because why not. I haven't decided on how I want to run it yet. However, it will most likely it will be more for corals and less for fish. I like idea of an AIO similar tohttp://www.badfishre...n-one-kits.html. I've heard the owner went MIA, so if needed I could always make a similar DIY. My other option would be going the route of a HOB skimmer and/or aquaclear 70 set up as a refugium. What are your thoughts? Any advice is appreciated.
