I don�t know what the old hands will tell you but, now isn�t the time to get cheap. Get the best quality fish stock you can find or get. Saving a few hundred dollars on a 2 acre pond projects cost isn�t a good trade in my opinion. You want a great pond, otherwise you wouldn�t be here. Not many times I�ve spent more than i wanted too and regretted it, But I�ve regretted cheating out almost everytime.
