The only thing that gets rid of ammonia in an uncycled tank is physically removing it by water changes. Adding a bottled chemical is like putting a bandaid on a broken leg - pointless, unnecessary, unhelpful, and could just hurt that little bit more in the long run.
Remove ammonia from an uncycled tank by doing water changes. If you have ammonia readings after a water change, it means you need to do another water change. Test, and repeat if necessary. It can take a few months for the bacteria in the filter to mature enough to handle the bioload in your tank. The important thing is to never change the filter media, or if you do, only when it is literally falling apart and replace it in segments, not all at once so you do not lose your bacteria colony. Also, do not add chemical additives to your water to try and fix a problem. Most problems in tanks are solved by adding fresh water to the tank. The only "chemicals" you should be using is a tap water conditioner to all new water being put into your tank. The fish store is there to make a profit, and selling you all these "miracle" solutions is a very easy way to make a quick buck off of you.
