first, you need to get a new test kit (not the strips either). id do a 50 percent water change, add the ammo chips back in and test the water, and test your water out of your tap too.. if the tank is only 2 weeks old, you should be at the end of the ammonia spike,and starting to build up nitrItes.. and have 0 nitrates still (because the nitrites havent been consumed and converted to nitrates yet).
its really weird that you have NO nitrites. if you have no nitrites and no ammonia then your tank isnt cycling-or is having a bacterial bloom. how long have your fish been in the tank? since the beginning?
