They also sell Aquashade to darken the water to keep it from growing.Neither are cheap but work well.I am working on my second gallon of the Aquashade so far this year. No ice cover and an early bright spring are hard on clear water ponds.Just follow the instructions on the bottle and you should be able to clear it up.
I imagine chlorine bleach would also take care of it.
