Meadowlark,

I would say if they are half as good for most as they are for you, they sure beat nuking your pond with repeated applications of copper products that build up in your sediments, and end up marching up the food chain. If that means you end up with copper in your system because you eat the fish in your pond I'll take a biological solution any day! \:\)

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
