Almost looks like I'm the only one here these days. One of my little stocktank ponds is a 50 gallon one. I'm using a "fountain" pump that seemed to be working okay (from my past). It's in one of those smaller filter containers. I set the flow to around 75%, and it was much too strong. So I reset it to almost the lowest flow setting........and it still is too strong....no change at all. The tube on it comes out of the water several inches. Something must be wrong with it. Is there anything I can do to decrease the flow?
