The milky color is most likely a bacteria bloom. It's not a bad thing, but it's not too pretty to look at. If I were you I would leave it alone for two weeks without doing water changes or adding any fish.
in 2 weeks add 2 small very hardy fish and start doing a 2-3 gallon water change weekly. Do you have any test kits? If not I would suggest you go out and buy the following: Nitrate, Nitrite, Ammonia, and pH test kits. You can fully stock your aquarium when Nitrate reads under 40, nitrite reads 0, and Ammonia reads 0. You should definitely be sure your aquarium is fully cycled before adding your main attraction fish. What kind of fish do you plan on going for? I would suggest livebearers or a school of tetras. Also what city you in? I'm in the Myrtle Beach area. If you have any more questions just ask.
