You can throw the paper tests, dip sticks, etc. away. For the hobby level you are aiming at they are useless.
Please get the kit I linked for you asap, it's only $20, and start measuring your water. Everyone literally in this thread or even on MFK will tell you this.
While you are waiting for your kit, if ordered by mai, you can find a local fish shop that does these liquid tests for free in store.
