So today I got my grandma's 30 gallon tank with every thing she had!!! The bad part is I have no idea what all the stuff does or is or how to set it up, so i need a little help...

Pictures:
1. I have no idea where this goes or is or what it connects to..
2. Still don't know what it is or where it goes or where it connects to... maybe something to do with an air pump...
3. Still don't know what it is what it does or where it connects to...
4. Still same thing as number 3...
5. Okay something I know an air pump... don't know what it connects to though...
6. A filter but I don't know where it goes...
7. Inside the filter... do I need anything else with it?
8. The heater!
9. The tank and stand
10. The tanks lid and where I think some stuff goes...
Well Thanks for looking I just seeing what will happen and just trying to see if anyone knows anything!
Thank you!
