I am new to all of this. In a few weeks I am receiving a 40b. I plan on creating an in cabinet filter & heater. Still debating on where to put the skimmer. Any advice? I started out about a year ago having freshwater fish (and I plan to keep them) but I’ve been looking into saltwater and I’m very intrigued by it. The amount of work for the tank does not concern me as this is already an almost full time hobby. Like I said, any advice would be great!
