just about got to the point where i can fill pond now ( aprox. 2500 gals) but i am still waiting for my stock tank to come in to make a filter , but I do have the skimmer and and uv and waterfall filter set to go, how should I go about seeding the pond with bacteiria or should it just be done by adding fish slowly ? maybe getting some filter water from someone elses pond? any advise on this thanks
