Hi, everyone. I'm a new addition to the list so I wanted to say hello. I've been keeping planted tanks for about 3 years now. I try to keep things as low-tech as possible, just trying to keep things in balance. I've been thinking about building an algae scrubber, hoping that it would help with the small algae problems that I have from time to time. Does anyone have any info on how well they work on planted tanks, or info on building one? Richard
