NO2, or nitrites, will be processed by bacteria and converted to NO3, or nitrate. The nitrate can be removed in many different methods but my favorite is growing macro algae in a sump.

New skimmers in a clean tank will make white bubbles until you have waste products to stick to the bubbles. Once the waste starts building up on the surface of the bubbles it will get more and more brown and lovely smelling.
