TOO HIGH AMMONIA

Question
Okay, I cycled my tank, tested my water, had it going for 2 weeks, all the stuff I read about. I put in two fish, they did great for 2 weeks, I put in 4 red mollies, they did great! Then, I got 10 neons (oh, I have a 55 gallon) and today when I tested my water (this would be the 3rd time since the tank set up) my ammonia is at 2.0 and my nitrite is at .25 (my nitrate is 0.0 and my ph is normal)... how do I get this back down? Just do another water change? Do I need chemicals... like ammolock, stress zyme... do I add these all at once? HELP, my two year old isn't very happy with me flushing the three fish that have died this week :( (I have the two original fish - can't remember what they are, 6 neons, and 3 mollies left). THANK YOU IN ADVANCE FOR YOUR QUICK RESPONSE.. it is more appreciated than you will know.  

Answer
You did everything great to set it up. However, once you put fish in your tank you are changing the enviroment which causes the water to actually recycle. Neons are not the best type of fish to get right away during this process because they are much more sensitive than some. I understand your child probably thought they were kinda cool but you will want to do about a 30% water change, test your water the next day, your levels should lower. I would stay away from chemicals at this point as it is always best to use chemicals as a last resort as they typically a short term solution with water quality issues. I would not add any more fish at this point until you get the water under control which most likely in time will balance itself out with a only a minimum of assistance from you. Once you get that where it needs to be then you can add more fish. Also, when feeding keep in mind the size of their eye is the size of their stomach, the fish should always eat 99% of the food you put in the water as the food that goes to the bottom simply begins to decay which is not helpful at all. Once you do the water change and test the following day let me know what your results are so if anything more can be done to help you out we can address it right away. Best of luck and happy fish keeping.
