I've used the aiptasia x with some success, although I feel like I'm fighting the ever-losing battle (just added a peppermint to hopefully help). The bubble algae does have more strength in the outer coating than you might at first suspect as well - they can take a small bit of poking at (I think I used the corner of a metal scraper to help pry some off...maybe that wasn't the best way to go about it, but it worked - I'm going to definitely defer to the methods of the more experienced though - sounds like the super glue method is a good one).
