Algaefix Algae Control For All Types of Ponds and Pondless Waterfeatures

I ordered as an algae controller for our pondless stream but the instructions on the bottle said it was intended for fish tanks. I have not tried it in our stream but I assume it will also work there. Also $15 shipping charge seems a little steep. Is there a less expensive way to ship small items? Thank you.

As always, great product from a great place! Thanks Pam
