I've let the nutrients rise in my reef tank. Unfortunately that has caused the growth of a little bit of brownish green algae. It's not a lot but it's building up on the rocks. I have a Cole Tang & Yellow Tang that pick at it, but they aren't doing the job. I also have a dozen or so Red Legged hermits.

What snails, urchins, crabs , or etc. might be valuable additions where control of this algae are concerned? Thanks.
