I've kept fish for years. Having more filtration than needed won't hurt a thing. Although it will set up a current in your tank that some species might not care for.

50gph filter is fine. Just don't use a 50gph pump to go with it. If you get a pump, try to get a variable one. Even if it isn't variable you can buy a sliding potentiometer to control its power input, and therefore its pumping speed. I have no idea what gph you would need for a pump on a 20gal tank, but it's probably some fraction of 20.

I suppose that depends how quickly you want to change over the water, if that’s the rating for the entire pump assembly and not just the filter itself.

Just add 30 gallons of fish to your aquarium and everything will be fine.

Are you planning on putting fish in that hurricane machine ?

Why do you need a filter?
