Doesn't some of that look like chara? Looks like some of what I got in my pond! If it is Chara best to to knock it down is Cutrine Plus pellets! That stuff works if you can afford it. The problem with Chara if thats what some of that is, is it can get even worse if you try to pull it out and the spore fall off and reseed into the pond.... It's something that is always going to be around in shallow ponds to some degree. I kept mine more at bay this year with some Aquashade I put in the pond in May. I only did it once and it got me through the main summer but mine is starting to come back now too.
