That's the one
A couple of things to be aware of.
Ammonia and nitrate have two bottles. Make sure you use them both, as per instructions. There have been members use just one of the bottles.
Nitrate - the instructions say to shake bottle #2 before using, and to shake the test tubes after adding bottle #2 before starting the timer. This is because one of the reagents settles on the bottom of the bottle and all that shaking is to get it back in the liquid. In fact, shake the bottle longer than it says before adding, and before shaking tap the bottle on the worktop to break up any lumps.
pH - there are two bottles, one measures from 6 to 7.6, the other from 7.4 upwards. Start with the 6 to 7.6 one. If the colour is the highest on the chart it will show that colour regardless of how high it really is, so then use the High Range tester.
Test the pH of freshly run tap water then let a glass of water stand overnight and test again. That lets any dissoved gasses gas out and the pH may be different.
It's a very steep learning curve. Shops will have you believe all you need to do is fill the tank, let it run a few days then get fish. If your fish die, they can sell you more. If the fish get sick, they can sell you medication.
We can talk you thought cycling, stage by stage. The first thing is to get that test kit and ammonia, and if you want to speed things up a bottle of Tetra Safe Start. When you have the ammonia and test kit, add enough ammonia to get 3 ppm with the tester, then ask what to do next.
