I know where you live
Okay, just to let you know, it's a waste of money. There is only one true way to INSTANTLY cycle a tank. That is to put already cycled media in the tank from a older, cycled tank. The bacteria can double their own numbers in less than 8 hours. So, if you put a small piece of sponge (or a small bag of gravel) into a new tank, with a fish or 2 (put them in immeadiatley when adding the media). Then wait a day or two (to make sure the numbers of bacteria are sufficient)you can add another fish. And you can keep doing that until your tank is fully stocked. Once it has been a week, there should be a sufficient number of bacteria in the new sponge/filter media that you can take the old sponge/whatever and put it back in the original tank. I do this every time I set up a tank. I have yet to have a spike in ammonia/nitrItes or nitrAtes.
