I've heard folks repeatedly say to limit light to control nuisance algae. I'm still waiting for someone to show me that it actually worked. You'd be surprised how little light some of them need, especially cyano.

I actually think its a good thing to let nuisance algae bloom in a new tank. How else are you going to cycle the wastes? Sure the bacteria will do some, but what about things like phosphates? What are your clean up crew critters going to feed on?
