So now I have some decisions to make about the order of my next steps. The system is basically ready to go. For filtration, I already have a filter sock, a skimmer and a gfo reactor. I plan on adding a marinepure block and another reactor for carbon. I'm thinking about going ahead with the rocks and sand to get things running and then add the marinepure and carbon reactor later. I can just use a media bag for carbon until then, and the bioload will only be a handful of fish for now. I'm waiting on corals until I can get a controller and the lights i want. Should I go for it and get the tank going, or would it be better to have all the filtration complete before I start?
