Actinic Lighting and Hair Algae

[WaterLogged]

I am fighting the same thing you are. My tank has only been up for 6 months though. Everything is brand new in mine. I contribute my problem to my crappy skimmer, but thats a whole diff. story. You might wanna try purchasing or even a DIY project and make a H.O.B fuge for your tank. Throw some mud, or sand, or whatever floats your boat in there along with your choice of macroalgae. Put a little light on top and watch the nutrient struggle begin. Although I have yet to do this I have done alot of research on it, and am getting a sump with fuge next month.
