Thanks everyone for your advice and information. Never an easy
solution, is there ! But at least we have choices, right! I
think I will return to the garden center where I learned about this in
a month or so and see what kind of luck they have with this product
before trying it myself. Since my algae season is usually quite short,
I may elect to bite the bullet and just get the big stuff out as I have
in the past.
Thanks again for your great responses,
Gary
