I used to own an Argo, and have a buddy with one. I have also treated my pond successfully with alum. I vote no on using the Argo for anything over pulling a garden hose around. They really aren't that stable or have much towing power when floating. It would take a LONG time to run 3500 lbs of alum dissolved in water through a garden hose. I used a good sized jon boat with a 55 gallon barrel and 2" pump set up for continuous distribution.
