Has anyone ever tried using turf builder for pond fertilizer? I apply Scott�s to my lawn this time of year and just had the idea that it may work in a pond. My normal fertilizer is Pond Pro (10-52-4) and my turf builder is 28-3-4. Also is a weed and feed a really dumb idea? Had the idea that if broadcasted of FA mays it may kill it and provide a little nutrients also. Any thoughts? Am I Crazy? The weed killer in my weed and feed is 2-4d, would that be detrimental to my fish?
