Thanks for the input

Got a yellow tang and it has not touched it. Any other ideas? It's out of control.

You can never garentee a paticular fish will take care of a problem. Algae problems are a result of excess nutrients giving the algae a food source. Unfortunatly it seams to take no time to have an algae problem but takes for ever to get rid of it.
you can pull calurpa out by hand and then perform water changes and make sure you are not over feeding, over stocking, and your bulbs are not too old

I had and emerald crab that would eat that stuff!

i had some but no longer i just reached in and pulled it out whenever i saw it, after a week or 2 it stopped coming back for good

My Foxface loves that stuff.

Likewise, I've bought coral that had some grape on the live rock base and it was gone within an hour because of my foxface.
