Do you have a good test kit?
If so good...
If not get one, you'll need it to cycle the tank...
You'll also need some pure 100% ammonia, smallest jug you can find.
the kind that is water clear...
Shake the jug, if it bubbles up, and stays frothy, no good,
if it looks like water when you shake it , great, that's the stuff you want...
When you get at least that much stuff together, you'll be ready to start cycling the tank...
I can/will help you all the way through it...
I applaud you for not doing this
AFTER you filled it with fish...
