Is this ich and how can I help him?

[Mr Bojangles]

well I got him a month ago and he was fine at the store, then at home he was fine. about 2 weeks ago he was stressed acording to the better half, she got him some good algae and it went away. Now he has more spots, smaller and many more! So I was hoping if I were to let this go by, if it would disaper again? (I did a search on it) Oh, all my numbers are the same and the only higher number is temp. My normal temp was 70~81, now its 80~83, and I was working on the new pump and spray bar yesterday so I was in there alot. Also if I had to treat him, would the best way to go to set up a 10g tank with a small filter and a NO light?
