Skimmer isnt needed on this size but if you do want one shoot for something rated for 75 gallon range which if I remember correctly the 4" reef octupus would be good (if it fits) and the return pump depending on your head pressure loss I'd go with either a mag 5 or 7. (the 7 would be my first choice) also, a ten gallon can be pretty hard to work with due to size so I'd consider using a 20 instead (preferably long).
