Hello everyone, I have been interested in reef tanks since I was young. I am 23 and looking for guidance through the journey. I have done tons of research, but am confused on somethings. I have purchase the 20gal long TopFin essentials. I understand this equipment isnt the best and dont mind upgrading, but dont want to spend money when I dont have to. I want to take it slow and end up with 2 Clownfish, Sea Star, CUC, Softies, and LPS. Obviously not at once and over time. I will upgrade to a bigger tank down the road, but i want to get an understanding of the flow of reefing. I have tons of questions and dont know where to start.
