Are Tangs important in a Reef?

Keeping your nitrates and phosphates low is a much better way to control algae than any fish or invert.

No, their contribution to algae control is minimal. Many don't eat any at all. And most tangs like 6' + tanks to be happy.

If you have an algae problem, a tang (or any other fish or invert) is not the answer IME.
