I'm thinking of getting a new reef tank in a bio cub 29. I wanted as much advice and tips before I actually start it. In the back of a bio cube, there is a refugium(usually you make it yourself) and I wanted to know about help on trying to set that up. I also wanted to know tips on water changes and possible anything you could teach me about. I am young so my experience level is low, so please help me as much as possible!!! Thank you in advance!!!
