Thanks for the tip Rainman, and yes the Koi comment was out of haste and would never be an option. I wonder if GSF would have gotten more peoples attention. Glad to here the Koi problem your customer had worked well for you however. I did experiment with GSF before the pond was renovated and can say that about a dozen GSF from the creek turned into about 1000 or so in just one and a half summers in 2 foot of muddy water They eliminated the abundant amounts of crawdads in short order too. Then, once the pond was drained, the dead fish stink lasted for weeks. I didn't tell my wife what I had done! She was not too happy with my newest hobby.


Fish on!,
