Organic algaecides

What have you found for organic algae control? I've used Green Clean, and it seems to work pretty well.

I don't use algaecides in any form. They do nothing to reduce the existing levels of NirAte and/or Phosphorus which is what supports the growth of algae. They are temporary fixes, at best, and require continued usage with increasing dosage. Additionally, there has been no studies done on what the long term health effects might be on fish and other aquatic organisms.
