JMAC,
The Clearigate is already loaded with surfactants so you won't have to add any. It might be worth an attempt. Keep us posted.
It would be nice to get developers to join forces with us types prior to the developing. There usually aren't any problems with weeds until after the developers are gone, so then it's out of sight out of mind for them.
It sucks turning down contracts, but I think we are better off with ridding ourselves with some of these messes. It's made my business more profitable. It took me awhile to figure that out. Some of these ponds just can't be fixed without a trackhoe!!
