Control of algae growth on concrete with coatings?

This isn't exactly waste treatment, but I figure the issue overlaps with it.  I have several cooling water basins, where even with chlorination, we get algae growth on the bare concrete sides.  The algae grows enough to form mats that slough off, and cause plugging downstream.  Discharge restrictions limit me on what treatment I can do.

My question is, does anyone have any experience using coatings over concrete to minimize growth.  I'm thinking that by sealing the surface, and making it more slick, the algae will not be able to grow as thick before it comes off.  I was wondering if anyone had tried something similar with good or bad experience.

Thanks for any help you all can give me.
