I have a 55 gallon tank with and im making it salt water. I have a fluval 305 on it and im running an aqueon circulation pump 950. Can you tell me what else in terms of equipment ill need. I know i need lights on the tank so i was looking for someone to help me with what type o should go with and i was also wondering if a protein skimmer is a necessity. I wanted to put a blue spot puffer, raccoon butterfly, dwarf lion fish and a niger trigger in the 55 gallon.
