I have read a WHOLE bunch on the KFW website about good pond management. I LOVE our states resources for gaining knowledge about taking care of the environment. Who ever knew SOOOOO much went into creating such a balanced aqautic environment. I have written down the number for Ken Jacobson. Thanks Chuck. When I get my pond up and going. I won't forget the people who helped out. It might be a while, but the good lord willing we ALL will still be here. Hows about a FISHIN.COM fish off/Tourney.....invitation only. TOO MUCH computer time....and not enough hand shakin.
