You didnt mention what type of lighting you have you need a uv light and a basking heat light. Turtle and reptiles in general need this if you dont have it make sure you get it soon before mbd sets in also check youre water since you moved maybe the water is bad and you might need a filtration sytem for your water this could not only affect you but also the turtle as fasr as the oily film I dont know maybe lubricant is leaking from the filter this is just a guess contact the manufacturer or it could be coming from the water good luck!
