How big is the pond? The biofilter looks way undersize. Just by the water flow it looks like 1000-1200gph pump. Why didnt you continue using round stone under the falls to give it a more natural look. Edges are nicely postion but then you go and put flatstone between, it looks choppy. Your mix of stone and plants look great its just the waterfall itself. Great job over all though for first attempt.
Thanks, I had no idea what size pump to get but that's what the store recomended. It's 1150 gph I think. The stone I got from a nearby stream. I guess I could have used roundstone for the fall, I just didn't think of it, but I'm not done with it so I may change it. My ducks I had to kick out of the pond because they started eating the moss off the stones. I wouldn't let them in it anyway because they would have it all fouled up in no time. It's about 10'x13'
You definitely need a larger pump and more bioconversion(filtration). The addition of a skimmer is a given. Without one, you will soon have a Muck Pit.
Keep in mind that the primary function of a pond is to support life and should be constructed to provide the optimum conditions for creating a healthy, self-sustaining eco-system. Sadly, many contractors overlook or de-emphasize this basic fact.
A coulple of updated pics. I put in a skimmer but kept the pump the same, my wife likes the sound of the water falling the way it is. I have a screen in the pond covering a lilly that's trying to grow, fish keep nibbling at it, also covering a plant on the side of the pond.
