I like the open look... My water seems to be staying in check. I was thinking of installing a "shelf" system, for future rock additions. Today, I have a snowstorm in my tank. I added some of that stuff that kills cyano two days ago, and now its snowing. I also scraped the back glass yesterday though, and there was a lot of dead corraline.. so that may be what I am seeing. Skimmer is working overtime!
