One thing to try is beneficial bacteria. It is sold in a powdered form here. Look for it from Aquascapes. Not sure who sells it by you or if it is approved for export. This product does not 'kill' algae, but rather 'eats' it as I recall. Another possiblity is to introduce more oxygen into the water with an aerating fountain. Some of these actually float on the water, others are hooked to a small pump on the bottom of the pond. Also, is this just a winter problem or year around?
