With readings that extreme, a couple of thoughts come to mind. The first (and I hope this is correct) is that the readings are wrong. The second is that something in the tank is causing the readings.
So, first: do you get the same readings on tap water that you have added the appropriate amount of conditioner to? If so, then most-likely, your readings are wrong. Regardless, how are you testing your water? And what readings are you getting from the tap water?
If you get sane, sensible readings from your tap water, then let's assume that something is wrong in your tank. If the readings are anywhere close to correct, your axie needs to come out of there until you can get things figured out and fixed. Do you have a suitable container or small tank that you can keep your axie in? You can keep your axolotl in a container that holds a gallon or two for a while, as long as you are changing all of the water often enough (like, twice a day, always with conditioned water of the same temperature, preferably conditioned with a good conditioner like Prime that locks up ammonia and nitrite for a while.) The container needs to be "safe", as in, safe from children, cats or other animals, getting knocked over, etc.
So on to debugging your tank issues ... I am guessing your tank isn't cycled yet. That would cause ammonia to go up. But it should not cause pH to go up, and from your post, it sounds like pH is above what you are expecting. So I am wondering what you have in your tank for decorations and substrate.
So, since a lot of the follow-on information depends on answers we don't yet have, how about you tell us what you found out about your tap water, what is in your aquarium (decorations, hides, substrate, plants, filter) and what you know about the cycle and if your think your tank is cycled yet. There are lots of people who will be glad to help you here. :happy:
