As this is a small tank and will have very little stock in it, 5ppm is perhaps too high. I would do a water change and get the ammonia down to 2ppm and then cycle at that level (i.e. wait for it to drop to 0 and then top back up to 2ppm). To get from 5ppm to 2ppm in a 5 gallon you'll need to change about 3 gallons.
