Apologies for the Subject Flashed at you ..BUT..I need to increase my knowledge level about what to do with the waste from fish farming both fresh and salt water. Anyone recyling it? I would apreciate any and all info in this area. I had huge files but lost a hard drive! I have multidrives and ZIP Drives now. Thanks for checking this out and let me know if you can help.
