The tank should be 0 for ammonia,nitrites and register some nitrate if the tank is fully cycled. Having ammonia show is probably due to overcrowding or feeding too much or not enough in the way of water changing.
I dont know if you are overcrowded and try cutting back with the feeding. Do two water changes a week of 30% and see if that helps. Only use the dechlorinator for now and see if you notice any change. Add extra aeration if you havent already got some.
