Flow rate for 12l tank

[mr. luke]

How much would be too much?
Im looking at an external but its rated as 1000lph...... which is almost 100x per hour?
Will be shrimp only unless i find some extremely nano fish (danionella sp.)

I have a Niagara hung on filter on my 12 litre tank, I have tried the 250 and the 300, would recommend the 300.

Over looking, even have a couple of plants growing on it lol:
