Athens? Cool my best friend was there for 8 weeks working the Olympics. Looks like a beautiful place. I am jealous.
Welcome to RS.
Research, research, and more research. If you have a question, just ask. People here are really really friendly so they will answer. Also try the search function. What I like best is just going to new posts and reading the entire thread. If it is something I want to follow then I subscribe to the thread and know when someone adds info.
There is lots to learn in the beginning. Can you give us an idea what you have now? Tank size, lighting, filtration, inhabitants, water parameters and anything else you know helps people know where you are coming from. Also we love pictures. So if you have any pictures of the setup and/or livestock that is great.
Hope that helps and welcome again.
Peace
Lynn
