Refugium For Tropical Freshwater Aquarium.

[Supersteve]

Hi everyone I saw a video on you tube in a fish store in America and there was a large discus tank with a refugium set up on it. He said that he hadn't done a lot of water changes on it I think he said six in a year. I'm going to start keeping discus soon and I know you have to do loads of water changes which i don't mind but My plan is to get a much larger discus tank when I move house and I just thought a refugium might be a lower maintenance way to go. Has anyone had any experience with a freshwater refugium filter.
