Fishless cycling

[smoutylad22]

Hello everybody, right I'm currently in day 16 if my fishless cycle. The 4ppm of ammonia I was adding was disappearing in under 10 hours. My levels on the 13/04/14 are as follows

PH - 6.8
Ammonia - 0ppm
Nitrite - 5ppm
Nitrate - 80ppm

I then did a huge water change the same day, didn't add any ammonia and a couple of hours later my levels read

PH - 7.6
Ammonia - 0ppm
Nitrite - 0.25ppm
Nitrate - 20ppm

The next day I checked the levels again with no ammonia added and the result are

PH - 7.6
Ammonia - 0ppm
Nitrite - 0ppm
Nitrate - 20ppm

The question is, am I fully cycled? Or do I need to add ammonia one more time and then wait 24 hours before testing the water once again. I really appreciate anybody's help and advice.

Thanks ?

Add about 2ppm of ammonia. Chech it again in 24 hours . If test show 0 ammonia and 0 nitrites then your filter is ready ? . 90% water change. Add your prime and start adding your fish ?
