manually remove the bulk, everyone says not to pop them, and they are right, but if your already infested, then its not really going to get much worse. get a pick or a set of tweezers and try to remove as many as you can reach by hand without popping, if you pop a few, dont freak out and just keep moving, then do a large water change and vacuum out all the loose bubbles, do this a few weeks in a row till you have most of them gone. then get a natural animal to keep the rest in check.
