HI Leandrah,
I would not worry at this point. The cloudy water is most likely from the binders The Biltricide uses... I would monitor your ammonia and Nitrite though as sometimes these get wacked a bit from bacterial blooms caused by sugars in some binders. The slime coat peeling culd be from several things, possible this fish is just a bit irritated from the meds. Hard to say. If its acting fine otherwise I would not worry. It could also be from the meds woking on Flukes.. These will cause irritation when they die.
hth,
