If tapwater after an hour then tested positive for ammonia, I would run another bucket of tapwater and add double the dose of PRIME and test for ammonia after an hour. If ammonia tested zero, Then for each water change thereafter,I would use double the dose of PRIME for all change water.
If after treating the tapwater with double the dose of PRIME the water still tested positive for ammonia, I would want to look for expiration date on water conditioner.For this tank, I might also consider a larger filter than the one rated for the tank or the addition of a small sponge filter.Both would provide a larger surface area for beneficial bacteria to colonize.
As has been already suggested, I would stop the use of any and all bacterial supplements for they too, irrespective of manufacturer's claims ,,have a shelf life that in my view is difficult to accurately predict. At the point that they cease to be the live bacteria that they claim to be,,, They then become ammonia producing organics for bacteria to eat. This is not wanted in ANY aquarium.
