1.25 months = 5 weeks. That's a brand new tank. ammonia of 4.0 = tank not cycled.
How is your tank stocked?
I would suggest a big water change to get the ammonia down and wouldn't add anything else until I get the water parameters under control.
How big is the tank? What kind of lighting are you using?
