I had a tuxedo and a short spine white/multicolored one (not sure of the name), both ate the bubble algae but the white one did eat way more but it also grew pretty big, pretty fast. I stated with both in my 50 and once the bubble algae was almost gone I gave away the bigger white one and the tuxedo was able to keep things under control. The tuxedo definitely worked for me as I didn't have anything else in the tank that ate algae but perhaps these things are hit or miss or it may depend on what other food sources are available as I didn't have much Coraline. I did however often move the urchins into places with lots of bubbles manually and usually the area would be clean the next day.
If everything is loose maybe the best solution would be to take out all the corals and clean everything manually, with such a small tank how hard could it be?
