Whatch the chemi clean for inverts I had it kill off ,a bunch of snails , tuxedo urchin ,sandsifting starfish it worked well its been 3 months and its totally gone but my critters paid the price , make sure that you make changes as to what caused the out break before you do the chemi clean or it will just come back

It never bothered my clam, snails, hermits, or shrimp. I don't think I've used it since I've had the urchin though. I always put an airstone in the tank to keep up oxygen levels.
