Is it possible to hold to much filtration?

I have a 10 gallan container a a 25 gallon pump will it hurt the fish?
Answers: That combo is fine. Keep an eye on the fish and if they appear to have difficulty swimming, adjust the flow so the current isn't too strong.
depends on the fish and the filter really. Some pumps can turn down the volume and speed.
Some fish love express currents and other prefer little or no water movement.
