I'd add more live rock and follow the water changes noted above. A sump is actually the most common filtration method here, most people in the hobby don't use the conventional "filters" as you might know them, they use a sump. It's another tank of water located under the main tank. There is either drilled holes in the tank with plumbing that drains into the sump, or an overflow box that uses a pump or siphon action to drain the water. The sump holds the skimmer, heater, and possibly more live rock and some type of macro-algae in a compartment know as a refugium. The live rock and macro-algae further help reduce nitrates, but even if you don't have a refugium compartment, the sump itself helps nitrate levels, as well as any other issues with water quality, because it adds more overall volume of water. More volume makes everything easier, which is why you'll see people say to run the biggest tank you can run. More volume also means that you can get away with less frequent water changes.
At any rate, the water changes should start you off, and make sure you clean your canister filter. As you delve into the hobby more you'll learn of other things that can help you keep the tank clean and healthy, and you might just swap out that canister filter for a sump.... it would certainly help. Best of luck!
