It could be a good thing, or it could be a bad thing. As long as you have a filter that's rated to handle a pond the size of the one you plan to use it on and it is rated to handle the flow you send through it, you'll be fine. In other words...make sure the filter is rated for a pond that's at least as big, if not bigger than your pond. Number 2....use it's flow rating as a guide. That way, you'll know if you'd be flowing too much water through it. Otherwise you could divert the excessive flow through a waterfall, or any other means you can think up, so that too much water doesn't flow through the filter per unit time.
