Looks like your cycle is done. Add 1 fish and test over a week to see how the tank responds.

I agree with @Kooma and @Gumbies R Us, nitrification seems to be established in your tank. You can either start with the first living creature in your tank like a fish or add something like 0.2ppm ammonia and see how long it takes to be nitrified again.
