My tank has been set up for about a year now I had two betta fish in there but one recently passed.Distinguishing between 0 and .25 is often difficult using the API kit.
To me, your result looks closer to .25. The only way to reduce ammonia, no matter the level, is a water change.
How long has your tank been set up and are you using a product like Prime? Are there fish in the tank?
