Shan, I have been using well water to mix and added CIDE-KICK. And like I have said, even if I went out and sprayed every other day I would still need to rely on a heavy rain or skreet it to get a nice looking pond.
I think at this point I have conceded defeat once again for this year. I will try SONAR early next year and pump down the pond like Greg suggests. How long can I expect Sonar to last, I have heard it is good for 4 to 5 years. My pond fills with runoff so any rain I get, the pond fills pretty quik and then runs out once full. Will that cycle out the treatment after the first year?? If so I think I may be SOL. I can't afford to spend $500.00 plus on my pond every season. It would be cheaper in the long run for me to fill it in and have a nice little water garden.
