Eric,
I have not checked the alkalinity since the water analysis I had done last fall, which showed a reading of 114 mg/l. The pond was drained and enlarged in the summer of '05. In the spring of '06 the water had a nice blue/green tint. Since then the water has either been tea brown, (which usually lasts all summer) or "black" (in the fall). My hope was to replicate that blue/green appearance this spring so that I could have another water analysis done for reference but no luck.

Cecil,
I'm taking LMB from my other pond and putting them in the BG pond.

Dave,
I'm not sure why they are not interested in the pellets. The day I caught the BG, I had fished with worms for about 20 minutes with no bites. After switching to grubs, I pulled one out on the first cast. Finicky diners I guess.
