What is the "ratio" that Chaeto actually consumes Nitrates and Phosphates? I have noticed I am starting to get small patches of hair algae- nothing crazy yet. But my Refugium is going crazy (growing a ton), so I was thinking maybe I need to add a small amount of GFO? Is my Chaeto sucking up Nitrates but not as much Phosphates? Appreciate any help, have never had hair algae in my display before so I want to jump on it earlier rather than later.
