The photos are the best thing about that article. Before, I have based my diagnosis on the photos on plantgeek.net, and thought I had hair algae. After reading this, I know that I have staghorn algae. Maybe I can get rid of it now that I know my Bristlenose won't eat it and I'm probably adding too much liquid iron supplement! I should probably add a DIY CO2 as well.Good article... but perhaps even more importantly, really high-qual photos.
