Pond Frog, two things that concern me about the chemical (Sonar) method.

First is it's price. I just priced it, and It's alot more than I would've guessed.

Second, is it mentions not to be within 1/4 mile of portable water intakes. I'm not sure what that means but my dug well is not too far from my pond, like maybe 100ft. Maybe I'm worrying about nothing, though?

Right now I think I'm gonna use a net, go out in the caneo, and see if I can't get most of it cleard off the surface that way.

thanks for the other info, too.

Jeff
