So I finally have my system officially up and running. All is doing pretty well, but I have been battling hair algae for a few weeks. I read that raising Magnesium levels can be very effective so I gave it a try. Yes, it does seem to have an effect, but it is not a complete solution. Although obviously receding, I still had a pretty large bloom. That was until I received my two tangs 3 days ago. I received a beautiful yellow tang and a powder blue tang. Both arrived healthy, happy and hungry. To my surprise, in three days they destroyed my hair algae problem. I have never read about Tangs eating hair algae. Has anyone every heard of this before? Could it have any ill effects on them? How can I grow more to keep them fed? (just kidding)
