In Texas, we're in the heat of summer and algae is a problem as well as organic debris. At the Pond Boss expo in Rockwall back in February I saw products from applied polymers. A log that hangs from a floating fountain. I can't afford the 300$ but I might get discounts on products like Aqua Control ClearAway. Normally the packs are thrown into the water but this is a unique situation. The water surrounds an island and is part of a larger water system. Water moves either clockwise or counterclockwise around the island and sometimes debris get stuck for days. I want to use organic instead of synthetic products. I'm planning on using a suet basket bird feeder or hamster ball as a dispenser and hang it below the fountain.

I'm not sure what I should do given the waterway is an odd design. I'll provide pictures later.
