There is really no need for anyone to pee in their tank. If you were to use ammonia you have to be carful to only use non-sudsy, non-scented ammonia and only add a couple of drops. Since you already had a fish in there the cycle has begun so the addition of ammonia isn't necessary. Get some Seachem Stability, add 2 capfulls to the tank on the first day and then add 1 capfull every day for the next 7 days. Test the water every day and watch the numbers. After about 4 days do a 25% water change, the water should be ok to add one small fish (acclamated slowly). Don't add more than that, if you overload the bio-capacity of the filter the tank will go into another cycle, test the water and watch the numbers. After a week do another 25% water change, the water should be ok to slowly start adding fish. Another easyway to cycle a tank is to add some filter media from an established filter from another tank. However if that is not an option for you do as I suggested using the Stability. Once the cycle has completed test your water weekly befor your water change and see where your nitrates are, this will tell you how often and how much water you will need to change to maintane the nitrates below 20 ppm and idealy below 10ppm. It is also a good idea to test your tap water to give you a base line so you know what you are putting into the tank. Two small water changes (25%) a week will be better than one lagre water change initally. If I left anything out or you have any questions please ask. HTH.
One other thing, please keep in mine some fish are more suseptable to even the slightest traces of ammonia & nitrite. Please indacate what you plan on keeping so you can be advised accordingly. Above is a basic instruction and might need to be adjusted depending on the species involved. IT IS A GOOD IDEA to get the water perameters any new acuasition has been kept in so you can acclamate accordingly, this will also minumize potential losses.
