There should be enough starter bacteria to drastically speed up the cycle ...unless you introduced some sort of disinfectant to it - bleach, H2O2, whatever - from stuff that you might have cleaned.

I'd just wait and skip the water changes unless you really need to put fauna in it quickly. Other than that, tons of plants are probably your best bet.

If you have fish in there, then do enough water changes to keep the ammonia under .25 ppm and the nitrite under 1 ppm.
Feed less.
Add more plants.
Use a dechlor that locks up ammonia, and do some research to be sure your ammonia test is reading correctly. Some tests will differentiate between locked up ammonia and free ammonia, and that is what you want to know. Some tests read wrong with certain dechlorinators. Best is to use a test and dechlor made by the same company.
While the tests show nitrite is present use salt (sodium chloride) at the rate of 1 teaspoon per 20 gallons. This will minimize the amount of nitrite that crosses the gills. 1 tsp/20gal is a very low dose and is safe for plants and fish.
