I appreciate all the information and I plan on adding a Gallon of Aquashade tommorrow, although since i'm in "full bloom" i'm not expecting much from this. I believe we are at the conclusion I have excess nutrients in my pond causing the algae to grow, so now i've just got to get a straight answer on how to remove them? I don't think algae growing on top of pond weeds is my problem as only about 10 percent of the pond has a weed problem and 90 percent has algae problem today. My grass carp have only been in pond for 2 months now and are only 12-14" long so i'm not expecting much from them yet. I figure next season hopefully theyll make a difference with weeds possibly but since they don't eat filamentous algae I don't look for them to solve that issue. So is alum pretty much my only option to get rid of this stuff? What about some of these algaecides? Does anyone even recommend a copper product such as Cutrine or something of that nature? Or is this just the band aid approach? Looking forward to more answers. Thanks.
