Safe Parameters

#1
Okay I just purchased the test strips because thats all I can afford, and it doesnt have the ammonia test. But here are the results after testing my water today:

NO4: 40
NO3:0-.5
GH: 300
KH: 180-300
pH: 8.4

Is this safe for my fish? I will try to find out what the ammonia is. Thanks.
