The way to have a high nutrient tank that is algae-free is to run a refugium and grow the algae there, use a variety of macro algaes that are fast growing and they will out-compete algae in the display tank for the nutrients.

I use chaeto, bubble, halimeda, and there is a bit of hair in there. All the algae in my tank is gone, and if there are any patches my foxface and tang clean it up in no time. I feed them with algae from the fuge actually, because there is so little algae in my display.
