Most color changing kits have a hard time reading smaller amounts of Ammonia, Nitrite, and Nitrate.
In normal cycling Ammonia is brought up to 2.0ppm at this level it is easy to see the colors and the transitions.
Missing a lot of information that would be helpful.
Brand of test kit used.
Water volume.
Amount and type of Substraight for the bacteria to grow.
Chances are your tank is cycled. Well it should be after six weeks but I will have to say BUT! maybe not.
The bacteria included may have not been good to start with.
You could purchase some ammonia, add a few drops test, add a few drops, test again until you get the level up to 1.0 or at least a reading you can noticeably see. From that point if the tank was cycled the ammonia will most likely be gone within 24 hours. You may never see a Nitrite spike as this can happen quickly but the Nitrate should noticeably rise.
Some advice for you though and you wont want to hear it but I feel you need to know.
Despite the hype and advertising of these tanks on how easy they are, it is simply not true.
Jelly fish and sea horse tanks are super cool, but these are the hardest tanks even for the MOST experienced to be successful with.
IF this is your first Saltwater tank as you say then I would go a different route for now and put the Jellyfish tank on hold until you gain some experience and understanding.
My goal here is to see that you have a positive expieriance in your new saltwater world.
