cb100, can you explain your setups in a little more detail or post pictures?
1. When you trash pump into the above ground pool, the water just goes through the soil back to your rearing pond? How do you get the muck through this 4" pipe that you were talking about? Do you use some type of pump to pump the solid debris into your manure pit?
2. This 10' device with holes, can you explain that plus the flat bar. The flat bar is iron to weight the end down? The flexible hose is to suction and the 10' end is the suction end so you can suction a 10' wide swath?
3. The t shaped pipe with holes, same idea, you are trying to suction off the bottom?
The jet ski adapter is brilliant and it is great to know that it does reach the bottom even of deep ponds.
Our kids for fun will use a short water ski tow rope (maybe 5')and hook up to the back luggage rack of our quad. They will then get pulled in a circle around the pond edge and they will wake board in the shallows. Just moving water in a circle at maybe 15 mph is enough to allow the sand that has silted in the 1" stone beds to wash away and all the stones look like the day I put them down. It clears the leaves very nicely.
If you had a gas powered trash pump on a cart with a rigid discharge hose in the shallows pointing towards the middle and washing 'down the slope' you could walk around the perimeter of the pond and probably wash out 3-4' of shallows quite easily.
