As far as my knowledge about the substance goes, you need to O/D to have a burning effect on algae. The normal dose just helps plants and that is enough in some cases as the plants inhibit algae better than anything else. BBA taught me that. I used triple doses of a similar product and all I got was livestock deaths until I tuned the water and had a steady and good plant growth. BBA backed away by itself. The O/D just kept it from spreading but did nothing to eradicate it.
