I have a 5 month old 10g nano that I'm fighting hair algae in currently. I want to be able to set up a small refugium with macro algae to try and redirect the nutrient consumption out of my main tank so I can get rid of the algae. I just have no idea where to start. Can a refugium be easily done in a 10g setup? inside? hang-on-back perhaps? completely seperate? Any advice would be greatly appreciated. I have time and patience but unfortunately not alot of money at the time so I would like to be able to do this as cost-effectively as possible. Thanks!
