You also need an ammonia source. The microbes you are trying to grow won't do that with no food source. As said, there are processes to follow to cycle an aquarium. Adding the nutrafin cycle won't do anything on its own. While the cycle product may contain those microbes you are trying to grow, with no ammonia present they will just die. With a fishless cycle that ammonia comes from artificially dosing ammonia into the water, with a fish in cycle that ammonia comes from your fish waste.
I would also point that I said the nutrafin product "may" contain those microbes. Scientific studies, along with hobbyists experience of these products show that most do absolutely nothing, and nutrafin cycle isn't one of the very few bacterial additives that have been shown to do anything beneficial.
As for your test strips, as you havent introduced any ammonia into the water, of course they will say everything is safe. All you are testing is tap water. That's not the point. What you want is your testing to say is that everything is safe when you are introducing ammonia. That way you know that there are enough of those microbes to consume the ammonia your fish will produce.
As for your test strips, personally put them in a drawer and get a proper test kit. Strips are notoriously unreliable, you have to buy a separate strip for ammonia (which is the most important test in a new aquarium), and you get a limited number of tests in a packet. A good liquid test kit like API Freshwater Master Test Kit covers all the tests you need, is more reliable than strips, and you get 100s of tests from it, so its better value for money.
It doesn't sound like you followed through on this piece of advice. Did you at least get the ammonia test strips? What precisely are your test strips saying?
You need to follow an actual cycle process. What you say you are doing won't actually do anything useful. It may say on the bottle of stuff you bought that it will, but it won't. All you are doing is circulating tap water, water conditioner, and a not very good bacterial additive product around your tank. None of the biological process you need to start happening will do so. You can do what you are doing for a week, a month or several years, but your aquarium won't cycle with no ammonia going into the water. When you eventually get your fish none of those processes will have established and it will be no different to adding the fish today. If you arent going to dose ammonia, you may as well get a fish and start a fish in cycle.
Here is a link to my fishless cycle process. There is a different route for a fish in cycle.
STAGE 1 – SET UP AND PREPARATION. Set up the aquarium, stand, filtration, lighting, heater if required and any other equipment. Fill the tank and run for 24 hours to ensure there are no leaks and that all the equipment functions correctly. Drain the tank. Aquascape including substrate...
