Hello All, I've had numerous freshwater aquariums before and 3 years ago I experimented with a 4 gallon Pico Reef that housed 2 emerald crabs. I took down the tank when they one day disappeared. My friend who has a beautiful 180 gal reef tank convinced me to try my hand at a another salt water tank since I have lots of equipment collected over the years and he had a few things he could give me that he has collected over the years. Yesterday I set up a 20 Gallon tank, I have attached a CPR Aero Force Protein Skimmer, Eskim350 Surface Skimmer and a ViaAqua Quartz Glass Submersible Heater. For Lighting, I am using an Aqua Illumination Nano. I am going to go out today to get a piece of raw shrimp to jump start my tanks cycling process. I am still fairly new to the saltwater hobby and I am still trying to decide what life to add into the tank so any suggestions on corals, fish, crustaceans, other life or even my set up it is appreciated.
