Not knowing what you have, or even what species of floating weed are allowed in the UK, it's hard to say. But koi and grass carp both love some types of floating weed. If it gradually disapperas, and the remaining weed stays green, then the fish are probably eating it. That's really not a bad thing. If it's dying in the winter, though, you should pull it out in late fall, as you don't want it rotting in the pond.
Aeration is very useful too. The bubbles don't add all that much oxygen directly, but the rising air column keeps bringing oxygen depleted water to the surface, and that will make a huge difference.
