If pond is new, do you have any vegetation growing in it? if not, planing to introduce non invasive species in certain key area will reduce your FA problem.

The FA are all over likely due to the fact that nothing is there to use the nutrients in the water. In a new pond, we often see an algae bloom until a balance is reached.

In fact its a good primer for a new pond, it will create a layer of organic sediments and that is needed for the bacterial fauna at the bottom. Balance starts at the bottom. Do not treat to quickly if the pond is new, time is on your side!
