Welcome newpondguy. It sounds like you have a good situation going, ie plenty of water and the basis of the food chain. Where is your pond located. Some of west Alabama has a high alkaline soil, which is good for pond production. Our pond/lake (80 acres), just north of Montgomery, has low alkalinity (ave 10 ppm) with a low retention rate. So we can not maintain a bloom with fertilization. I started feeding two weeks ago and have had a good response from the bream, crappie, golden shiners and a few cats.
