NOOOOO!!! Don't do it!! Cattails can easily get out of hand and invade your pond. I'll let the experts on aquatic plants chime in, but I'm sure they'll agree! Have you tryed dying your pond? Pond dye can shade out the sunlight that the filamentus algae needs to grow. Just one idea...
Hello Sue. With all due respect and as I mentioned to "CreativePond":
"That said, I do believe that a section of cattails adds to the beauty and biological diversity of the overall pond ecosystem. Cattails are easily managed with very small concentrations (3/4%) of glyphosate (Aquaneat, etc.) containing products."
Cattails IMHO provide significant value to aquatic ecosystems. I do understand however, that each and every pond is managed in a manner that is consistent the particular needs and wants of the pond owner. The common misconception that I want clarify is the fact that cattails are easily managed with small amounts (3/4%) of glyphosate and spreader/sticker. The same applies to our American White Water Lily.. "Nymphaea odorata"
I am a little surprised that you did not suggest the benefits of aeration for small ponds. Your Vertex diffused bubble aerators are the most efficient and effective means of aeration in ponds and lakes in my opinion. Here is a reference you may be interested in.......

John Madsen • John: Aeration has been widely used to control filamentous and planktonic algae. Generally, it works best where aeration will prevent the formation of anaerobic conditions that cause the release of phosphorus from the sediments. CO2 don't have anything to do with it.
