Ammonia in tap water?

After being out of the hobby a few years i recently set up a couple tanks, one being a small planted shrimp tank for some CRS and Neos, other for some fish only. I have always been on well water and never did much water testing and had some great tanks/fish. But late last year we had to get on town water, no chlorine etc they said, after filling my tanks though i got some Prime to be sure. I used pure Ammonia to cycle and never really checked Ammonia after Nitrate was high, when it got to 120, i did a huge WC to get ready for the shrimp, suppose to get them tomorrow, but after the WC the ammonia was higher and now have nitrite again:-(.
It looks like, with API test, Ammonia is close to 0.25, is that high for tap water? Adding prime to the tank does not make it completely go away, should i add more prime and age/aerate the water or would that help with Ammonia?

Are you dosing nitrates? If not, it sounds like your bacterial colony may just need to grow a bit more to handle the amount of ammonia added?

Do you have plants at all? I would put as many stems and floaters as you can to keep the ammonia / nitrates down for those shrimp.

As for Prime, it does not remove ammonia, it just binds it up for something like 24 hours in a non-toxic form that can still be consumed by plants and bacteria. This will still show up on the API liquid tests (afaik). You'll want to test daily and do water changes with Prime as needed.

This tank is planted, i have not dosed anything, i just did a water test, i did not change any more water or add anything to the tank after the large WC on Friday, Ammonia went from .25 to .50 and nitrite from less then 1 to 2.0, how is there more ammonia when nothing was added to the tank?
I also set up a new tank, no plants yet, with new sand and new everything, only been up a few days and ammonia in it is at 4.0 already!?
the test still shows only 0.25 Ammonia in the tap water so i dont get why it gets so high in the tanks?
