What is a good algae grazer?

Thanks ReefGeek, I have been using a nylon brush on some of the rock, But Im concerned about the suff I cant reach near the base (30" deep) and I dont want to disturb my aquascaping by removing rocks to clean. The agae is starting to spread to other rocks with some hairs reaching almost 3" long. I thought about waiting it out but would also like to take a more proactive aproach.

If I go with the sea hair is there anything else I should be warned about besides it starving? I was concerned about it crawing into my pluming from my overflow.
