Is this Red algae?!

It should pass. If not you can eventually use chemi clean. It's the normal occurrence at the beginning of a tank though
 
I been keeping the light on for 10 hours a day is that too much? Should I do a few water changes?

yup what smith11 said... I have mine running for around 10 but they ramp up and down... not much light at all for about an hour in the morning and hour in the evening.
