So it's just starting to grow. Not bad yet should I do anything to get ahead of it? I need to get some plants going as well.
I rarely endorse attempts to eradicate all algae or vegetation in a pond. Nature is a formidable force and will never cease Her efforts to fill a void - especially in ponds. Heck, I fight algae in my swimming pool all the time, sometimes successfully.
If it's just getting started, monitor its progress. You can often curb the proliferation of algae by using various traditional tactics to limit sunlight-transmission through the water-column. If algae begins to get unruly, manual removal or modest algaecide treatments may be in order.
Ultimately, your objectives and tolerance are the best guides for action; but just don't wait until the forest is ablaze before you reach for a water bucket (pursue corrective measures).
