Hi Andrew, And welcome.
I would take the airlock off and agitate the cider a couple of times a day to mix the liquid and (yes!) introduce some air into the cider. When the specific gravity reads close to 1.010 or 1.005 I would replace the airlock. And that may be today or by the end of the weekend. (I just fermented a gallon of apple cider - no added sugar - at a starting gravity of 1.045 (I think it was ) and it took only two days to drop to 1.000. The ambient temperature was about 70 F). I am not looking to make a wine from this but a hard cider at about 6% alcohol by volume or ABV)
It looks like you have significantly less than a gallon so my suggestion would be to either add more apple juice and sugar (at a gravity of 1.070) or else look for smaller containers that you can allow the cider to age without exposure to air. The larger the headroom in your carboy (the space between the surface of the liquid and the bung ) the more air you are exposing the cider to. During the first few days or weeks while there is active fermentation the yeast need air but when the fermentation slows or stops that air now binds with the wine and oxidizes it (a bit like rust). My $0.02
I purposely left that much head space because I had one batch foam up so much it bubbled out of the air lock the air lock has slowed from one bubble every 2 seconds, down to 1 bubble every minute to a minute and a half. Unfortunately right now I have to get ready for work. I have about a cup to a cup and a half of juice I can mix in right now, all other suggestions will have to wait until Saturday. Thanks for the input
