Perry infection

First time making Perry, and have a greenish-brown blobs floating in it. Added my sulfide, waited 36 hrs and put in my yeast and nutrient. This all happened in about 5 days and its growing very fast. Can I stop this? or is my Perry done?

Could it be the yeast? I used White Labs Floral Sherry Yeast WLP700. I heard from an old timer that it does real well with pears. The same funky color and lumps are on the bottom of the carboy as well. The Perry does not have any foul odor at all, it smells great. Its growing very quickly too-
