Green Clean Pro is a lot easier to find a nearby retailer. Some fish farms, and pond management companies handle GC Pro. However, since GCPro is the same active ingredient, it also ships hazardous material. Get some and try it to see if it works for your particular FA problem. As I mentioned, for FA that is more established, taller, or even floating it will take more product. When FA is floating is has gotten way ahead of you. Once you get it knocked back don't let it get ahead of you. Treat the FA when it is 1"-2" tall when using GCPro. Not all FA is the same species. Some will be more tolerant than others- depending.
