Have you totally cycled your aquarium?

How long has your tank been set up and what are the filters?

Do you have live rock?
If so it is important that this live rock is seasoned and been in a healthy tank at your LFS at least 3 weeks (more is better), otherwise this can have the opposite effect on ammonia/nitrite removal as well as nitrates too.

I would recommend reading this article about marine basics:

And this article about the Aquarium nitrogen cycle:

Please add more info if possible for others to help

EDIT:
I agree with finatic that a nitrate level under 20 is good, however to make a good diagnosis we need more parameters and the age, set up, and other methodologies of your aquarium to make a clear statement of your aquariums health.
