High nitrate in new setup (help required)

I have had my 60g setup up for 2 weeks now. It has a moderate amount of plants and some small fish (black neons, regular neons and corry cats) I have also been adding nutrifin cycle to get the tank running properly. I just got a new hagen master test kit today and decided to run all the tests. My ammonia is zero I have been keeping an eye on that and has remained low since setup. My problem is my nitrate is off the scale over 110mg/L and my nitrite also off the scale over 3.3mg/L. Should I just maintain regular water changes and let the tank sort itself out or should I be doing something else. The fish are not showing any signs of stress and I have had zero fish loss since adding them.

Any help would be greatly appreciated.

i don't think water supplies add anything like Nitrites to water, so that is just the signs of the nitrogen cycle finishing (if ammonia is 0 now). The last of the Nitrite spike is being converted into NO3 right now.

As for NO3, just let the cycle finish out, and re-access after. Seems a little high with only having small fish, which would lead me to think Testkit malfunction. Have you tested it on your tap water as well? I can't imagine cities adding that high of NO3.

I would just add more plants and check those kits as well. Fast growing stem plants will handle any and all nitrates you have and before long you will be adding nitrates to the tank instead of worrying about them.

If the fish look healthy I wouldnt worry but get more plants and have your water tested at your LFS to double check.

Thanks for all the advise. I was thinking of taking a sample to the LFS to check that the kit was correct. I will keep an eye on it and see how it goes.
