Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Homemade weed killer. Pond safe??

Backabit,

I second all that Bob says about the little amount of salt being of no concern for the health of your pond. In fact after enough applications you might get enough built up in the soil to prevent future vegetaion (doubtful though), which is what you are trying to accomplish. I too have experienced farming fish at 3500 ppt salt. Fish farmers around here dump salt by the dump truck load in ponds to help their fish. On another note, you should be able to find locally some 41-53% generic glyphosphate product for @ $20/gal. Mixing at a rate of 2-3 oz. per gal and an oz. of surfactant or soap, that comes to a big savings over what you are paying now.
