Don't know about anybody else but I have no idea what "salt fighter size" would mean, doesn't make any sense at all. The other comment however does make it sound like possibly one of typical containers of salt sold at the LFS (local fish shop) and pushed as an extra on freshwater beginners even though its not needed. The dechlorinator sounds normal.
The members may need to know your exact equipment and more detail about what actions you've taken since it was obtained - I don't think its clear yet whether you've been sold and are running equipment, some of which may only be appropriate for marine.
In either case, the idea that a tank can be filled with water by a beginner, let sit, and then fish put in within a week is totally wrong if the beginner has not first learned some of the core aspects of preparing water for fish. Please do not get fish yet.
If we determine you really do want to learn Freshwater Tropical fishkeeping then you've happened upon one of the best possible places to learn it. The members here are great. Lots of them should be able to comment and help you figure out what's what.
