Please read the suggested threads on cycling.
You have at least two things working against you. You do not yet understand what it means to cycle a tank, but the readings should fix that, and you do not have a test that any of us would accept as useful. The only test worth using are the ones that use tiny test tubes and liquid reagents to read your water parameters. Many of us use the ones made by API and marked as their Master Test Kit. Almost any other liquid type test kit will do as well for you. What you want to be able to read during a cycle is the ammonia and nitrite levels along with the pH. The nitrate levels will guide you in doing adequate water changes after you get cycled but is really not needed to cycle a tank's filter.
What you have bought is a tank and components that may some day be a stable environment for your fish. Fish and any decaying wastes produce some ammonia. We say that ammonia is toxic at levels over about 0.25ppm. It is a slight over-simplification but is a good guidance number. Fortunately there are bacteria that will convert ammonia into nitrites. That gets rid of the ammonia. Now the bad news, nitrites are also poisonous to your fish at around 0.25 ppm. The next bit of good news is that nitrites can also be converted, by still more bacteria, into the almost harmless form nitrates. Nitrates are something that we use mainly to decide how often to do a water change. When nitrates have grown to more than 20 ppm above the tap water value, it is time to do a water change.
Where do these bacteria come from? That is easy. There are a few that survive the typical water treatment plant's treatments with chlorine. They arrive in very small numbers in your fresh tank water. What we do is feed them and grow them. Since they do best on surfaces, we ignore the trivial numbers that exist free floating in our tanks and focus on developing the colonies in our filters. The cycling threads walk you through the critical aspects of growing those bacterial colonies but please feel free to return and ask questions as you move through the cycling process over the next few weeks.
