Here is what to do-
1. Change the water before you add the ammonia, in fact change it tonight.
2, Follow these directions from Dr. Tim's site:
Using DrTim’s Aquatics One & Only Live Bacteria: The best and easiest way to fishless cycle is to combine adding the ammonium chloride with our Live Nitrifying bacteria. When used in combination, these will cycle the tank in less than one week. Again, do not add too much ammonia. We make it easy by providing a bottle of reagent grade ammonium chloride that is at a concentration such that adding 1 drop of solution to 1 gallon of aquarium water will result in an ammonia-nitrogen concentration of 2 mg/L (ppm).
The procedure is to add the ammonium chloride solution, shake the bottle of nitrifying bacteria well and add it to the aquarium. Measure ammonia and nitrite the next day and record. Add ½ dose and wait 24 hours and measure again. By day 5 to 7, you should be able to add 1 drop per gallon and the next day, ammonia and nitrite will be 0.

Some fast notes to clear up any potential confusion-
If you did not have the ammonium chloride, use other ammonia in an amount designed to produce 2 ppm using the ammonia calculator on this site.
Before you add the bacteria do shake the bottle well and also turn of the tank lights. Leave them off until you test the next day. When you get to the 24 later hour point, test for both ammonia and nitrite. Then add 1/2 the amount of ammonia you did the day before. Do this no matter what your test results are.
Do not add any more ammonia and continue to test daily.
When you do see 0/0, add the same amount of ammonia as you did the first time (the full amount). You should then be able to test in 24 hours and get 0/0. If not wait until you do get 0/0 and repeat the full dose and test.
This can take anywhere from 5 -7 days for most people. Do not worry if your tank requires more. One thing that can make things go faster is using more bacteria than is suggested for given tank size. The more one starts with, the fewer times they must double to reach the needed numbers to be able to process the 2 ppm in 24s. But most folks would be happy to be fully cycled in about a week .
Do not change water until the tank is cycled and then do a 50% or more change before you added fish.
