You won't be able to prevent algae growth. That's a natural response to perfect environmental conditions. The good news is that it will primarily grow on the flooded terrestrial plants. More good news is that, as water temperature changes, algae will ebb and flow. Unless it inhibits enjoyment of the pond, I wouldn't worry too much about it. I bet it will go away by mid-May where you live.
