Nice looking tank. Sounds like a herbie style overflow system. There are quite a few youtube videos out there that can explain how it can be set up. Here are a couple of really good threads to help get started. https://www.reef2reef.com/threads/cycling-an-aquarium.306554/unreadhttps://www.reef2reef.com/threads/t...ng-up-a-saltwater-reef-aquarium.138750/unreadBest advice I can give right off the bat is to invest in an RO/DI unit. It will be much easier than lugging buckets of water from the LFS, and you will always have the peace of mind associated with knowing the purity of your water. Of course there will be other equipment required. You can get a general idea of what you might need through your research. After that, I'm sure you'll still have plenty of questions. Ask away!
