I am having trouble locating a price for the sonar PR, Is it as costly as the AS? Is this Sonar PR sold in a granual or liquid? I havent located any on the net. If I could dose it in the winter for preventive measures I would do so because once my wm and dw get going it takes off very fast and I dont want it to get away from me next year. I am enjoying my clear pond way too much to let this happen.
