Put in another 350 lbs. and it made a world of difference. I put it in two days ago and the water is clearing extremly well. Not only is the water clearing but the fishing is improving. I'm catching bass on a regular basis now and the fish in general are getting there natural color back. I was starting to think there were only a copuple bass in the pond but I belive they can see the lures now. I'll start taking pictures and posting them. dw2332 did you ever find your alum yet?
