Cycling a tank is simple. There's literally nothing to it, it will take care of itself.
THe reason why people stress cycling your tank is because the majority of individuals in the past used to buy an aquarium, and then go to their local pet store, buy a fish, and stick in the aquarium expecting it to take care of itself with just simple tap water changes and feeding.
Finally, with the advent of the internet, the process of cycling a tank is published everywhere.
Those test kits are simple to use. They are color coded, and explain very simply what results you want to see, and what to do if the results listed don't come up right.
Cycling a 1 to 3 gallon aquarium? Big deal. Just keep one fish in there, and get the basic 5 in 1 test strips and the ammonia test strip from a pool supply store, and you'll be just fine.
The general rule for cycling is very simple, anyway, just change 10% of your water every single day at exactly the same time every day, and then on the 7th day, change 50% of the water.
After 3 weeks your tank will be perfect. (make sure you use water conditioner if you are using tap water!!)
