Bubble Algae
 

Ok its starting to get out of control now its on all my rocks. Im debating if I should get a foxface again. to deplete the bubble algae. or is there something else.

That would explain why I have no bubble algae in my display and only in my overflow.

I love my Foxface he is the big dumb ox of my aquarium. So peaceful but if he wanted to I am sure he could mess em up.

ya the last one that i had was a great fish he wold eat right out of my hands and let me pet him on his nose. but he was eating the LPS

i heard emerald crabs will sometimes eat bubble algae

I had the same problem, tried other measures but the only solution was a rabbitfish!

My purple tang actually does a great job at eating valonia. But I think I just got lucky... then again it also eats trachyphyllia.
