For an interesting take on algae in ponds, read Richard's blog. Remove what you can by fishing it out. Leave it by the pondside for a while so that pond creatures can crawl back into the pond. If you have a large pond, the traditional method of dealing with algae is to put barley straw in there in spring, taking it out in the autumn. However for small ponds, you can buy liquid barley straw extract from garden centres, which does the same thing. It's good to remove dying lily pads, but living ones can help promote the shady conditions that you need. If your pond is in the sun, try planting shade-giving plants around it. Good luck!
