I've never tested for Nitrite I meant..
The tank cycled with fish in it about a month ago.
I last tested the water yesterday and both Ammonia and NitrAte were non-existent, I've never tested for Nitrate.
I'll take some water to the shop tomorrow and get them to test it.
I add fish by leaving the bag in the water for around 40 mins, adding tank water every 10 mins or so and netting the fish out.
I change around 15% of the water weekly, siphoning the gravel and cleaning the glass.
If you don't have one yet, I strongly suggest you get an APi master test kit for yourself. You will be able to know for yourself what your water is doing immediately. One of fish keeper's best friend. And plant keeper's, BTW. OS.
