 My pontoon dock and channel is very bad with water weeds.  Can I use copper sulfate  to kill the weeds with out corroding my pontoons.   I have a 2020 Godfrey Sweetwater.  My first use the motor water inlet clogged in less that 100 yards.    Looking for a suggestion,  Thank You

    I got a response from my dealer, which also owns and operates a marina.  Here's what he stated when I asked if the aluminum pontoons would react to copper sulfate:

    "Copper sulfate on its own does not react with aluminum. If added with sodium chloride, producing a vigorous displacement reaction which illustrates the reactivity of aluminum. The solution gets very hot, the aluminum dissolves and red copper becomes visible."

    Hope it helps
