Sorry, you guys will get so sick of me asking all these questions! you`ll probably say forget the fish, get yourself a hamster!!!( i`ll empty the water first of course, they dont swim too well!!)

I`ve just tested the tap water, the results were surprising to me, not what I expected at all!
Ammonia 0ppm
Nitrite 0ppm
Nitrate 20ppm
PH 7.6
Not sure where the ammonia reading is coming from? is there any in the aqua safe or the cycle I added at the very start? confused as to where the ammonia has come from? what do you think?
