Thanks for the comments. The pond has a recirculating pump, it used to be part of a jacuzzi, pool pump. I bought the skimmer box and waterfall box, the rest I made myself.
The skimmer has one of those mesh laundry bags to catch the big stuff, leaves etc. Then the water flows thru a filter media pad then into the pump. After the pump it goes thru a UV light, then up to a pond waterfall box. In the waterfall box I put 2 mesh bags with lava rocks, to act as a biofilter. The water flows up thru the bottom of them, and then over the waterfall. I have taro, watercress, sweet potatoes, all growing in the waterfall too.
The skimmer must get cleaned out once a week or so. Just pull out the mesh bag, and filter pad, hose them off and reinstall. I pull the lavarocks out of the waterfall box and hose them out about twice a year.
I don't have any mosqueto fish, mosqueto larvae are not a problem because of the bluegill, goldfish, etc.
