I am still battling hair algae and some pockets of valonia. The display portion of my tank is about 25G. I added one emerald crab about 4 weeks ago. He has doubled in size since then but I have not noticed him eating valonia yet, that was the job he was hired for. Maybe I will add another emerald crab.


But I do have two urchins who look like this:




They keep the algae to a minimum on the back side of the rocks but rarely come to the front where the algae is the worst. Maybe if they get hungry enough or I keep the lights off for a few days they will work on the front of the rocks.

I have peeled a few of the larger algae bubbles off by hand.

I am thinking of getting a sea hare to help out with the hair algae, I have read somewhere that some people have seen them eat valonia as well.
