Hi again! 
I hate to repeat some things I've posted here but I posted on another site and so far nobody has answered so I figured I would put the same post on AC and see what advice I might be able to get.
"We started a 10 gallon tank 6 weeks ago. All was going well with it till the ammonia spike fell to zero and the nitrites started showing up. The nitrites stayed at 2.0 for 2 weeks and the nitrates at 7.0 We then got another tank, 58 gallons and put bio spira in with the fish that we had in the 10 gallon. The 10 gallon is now empty of fish. I did a 50% water change and the nitrites are still 2.0 and nitrates 5.0. That is my first question, how do you get the nitrites to go to zero? I'd like to get the 10 gallon ready for fish again and won't put any in until it's good to go.
The second question is, when testing the water with the bio spira how should everything go with the ph, ammonia, nitrites and nitrates? Do they stay high for a day or so and drop? It's our first time using it and there really isn't too much I can find on that info. I have tested twice since putting it in and the ph is 7.2-7.5 the Ammonia was .25 and now is 0, the nitrites are 3.0, nitrates are about 15. Those didn't change from one test to the next. Thank you in advance for any advice."
