Getting into FW

[Stab_Master_Arson]

I have a 60 gal tank with stand and lights sitting in my garage and I am thinking about making it a FW tank.

I have to be honest, the only FW fish I have ever kept are feeder goldfish when I was 6.

I plan on doing some research via the net later but I thought I would seek some advice from FW fans right here first.

Stupid question #1

What do I use for filtration and nitrate control?

Stupid question #2

Do I skim?

Stupid question #3

Can I use my saltwater canister if I clean it out?

Any input for a beginner would be great.
