    Blows in the Wind

    The product is very fine. This helps spread it into a pond as long as you cast it with the wind. The product is way too fine to spread against the wind or in high winds.

    no support

    I sent an email saying only half of my order was delivered and I still haven't received the other half. I sent the email a week or more ago and still haven't had any response.
