I'd check your test kit is working properly as i can't see how you can have a zero nitrate reading as it is the end product of the nitrification process and can only be removed by water changes. Check your test kit for a use by date.

i did the test again last night.. zero nitrIte and amonia... don't have a test for nitrAte.. and the test kit i use is still good.. no expired test there
