You want 0 ammonia and 0 nitrite. It looks like your test strip doesn't do ammonia though. You can use salt to bind the nitrite or do a water change to get rid of it.
It sounds like your tank isn't cycled or the test strips are wrong which could very well be since they are known to be inaccurate. I would pick up a liquid test kit ASAP.
Here are the instructions for the salt:
"To add 10 ppm of chloride for every ppm of nitrite in the water, use the following steps:
1. Multiply your nitrite reading by 10. This will give you the needed mg/l of chloride to will need to add.
2. Calculate the actual volume in liters of water in your tank. If your volume is in gallons you must convert this into liters. (As a rule, using the advertised volume of the tank at about 85% will put you in the right ballpark.)
3. Multiply the number in #1 above by the number of liters of water in #2 above to get the total mg of chloride you will need to add.
4. Because salt is roughly 2/3 chloride, you must multiply the number calculated in #3 by 1.5. You now know how many mg of salt you should add to the water. Dividing this number by 1,000 will convert this amount to grams which are easier to weigh for most people.
5. Do not add salt directly to the tank. Remove some tank water to a container and mix the salt in that, then add the salt water to the tank spreading it around the surface.
6. The amount of salt needed is not very much compared to a brackish or salt water tank. So don't worry about the salt harming things, especially for the short time you would need it in the water.
You will need to continue testing for nitrite because any rise may mean that further salt additions are needed. Once the cycle is done, or even as nitrite drops, you can reduce or eliminate the salt from the tank via water changes."
Did you cycle your tank? If so, how? What size is it? If you don't know what cycling is have a read of
THIS.
Have you tested the pH of your tap water after it's sat out for 24 hours? I am wondering because 6.0 is the lowest on your test, it could be that or it could actually be lower.
