I have about a 1/4 acre pond. Last year I had a major problem with duckweed and watermeal. I treated it with Sonar and it cleared it right up by fall. I thought I had the problem whipped, but in the last 2 weeks, it's started coming back. Can anyone tell me where they have found the cheapest place for me to purchase a pint of Sonar? Thanks in Advance!
Tony,
