Remove the urchin. It's diet is coraline algae.

Yup, definitely. Urchins love coraline algae.

Can you give more info about your setup? Size tank, lighting, alk, calcium, ect...
It's true urchins eat coraline, but, they also poop it and spread it all of the tank, and thats a good thing.
Lower lighting will also help certain colors of the coraline, the purples I believe. So if you have pink, well the light may not be strong enough to support it.
Get back with some more on your setup.

I have them in a 20g and i'm going to put them in my 55 when I get the rest of the equipment for it. All my levels have been fine when I test them. I just have a standard light though.
