Of turbos, astrea, trochus, blue leg hermits, red leg hermits, emerald crab, lawnmower blenny, and so on and so on, which would have the best chance of controlling hair algae? I'm willing to spend whatever. I have completely taken my tank down, srubbed every rock individually, and it is now coming back. Water is perfect with zero to almost zero nitrate, and zero phosphate. I have tested my water source and it too has zero nitrate or phosphate. Where the heck is it coming from!?!?!? Obviously I cant stop it, so I guess I just have to control it. Any suggestions?
