I will add this, but before I do want to mention I'm very new to this.
I got my LR and SW from the lfs and have basically not shown a cycle or a very small cycle. It's possible I'm still in my mini cycle. My ammonia has never been above .25ppm and my ph is steady at 8.2. There is the general rule of thumb; ammonia, nitrite, then nitrate, however I've got a fresh and an SW neither of them have been a textbook cycle from my understanding of how it works. I would suggest you get the standard API Saltwater Test kit, and the Reef Master Test Kit. The first is for testing and ensuring your Nitrogen cycle is going correctly, or at the very least so you can keep an eye on it. The second is for you to be able to test for stuff your corals will need. Both my fresh and salt were seeded so I have/am going through a mini cycle and from what I've read and experienced it's different than a standard Nitrogen Cycle. I hope this hasn't confused you, I was only talking about what I've experienced with my own tanks vs. what I've read and been told. Remain calm what others tell you and what you experience may differ, that doesn't mean you've done something wrong it means there are no absolutes in this world.
