Recently converted to purina 500 and can’t believe the results, pond is 9 years old and this is the first time that the catfish come to the surface to Hoover feed up . They were stocked in 2014. Usually just CC but last night at dark threw out feed and the blues came up, probably a dozen of them. The bg are looking good and some appear to be around a pound maybe more. So it pays to use high quality feed
