Hi. I posted last year about my sandpit but couldn't get logged in.
Same pond, different name. To update your information, 80 year old sandpit, 3 to 4 feet of black muck on bottom and a horrible duck weed problem.
Last fall and this spring I removed 20 some trees from 2 sides of pond to help with air flow. This did help with keeping a little more open water, but will not solve problem.
This summer I have acquired 2 4 inch Gorman rupp thrash pumps with deutz Diesel engines.
My hope is to install both pumps on floating platform, with one pump with a suction line going down to around10 feet and discharging over the edge of pond into a field. The second pump will pick up clean water and discharge through a smaller dia pipe connected to the suction line blowing a hole into the muck and diluting the muck for easier removal.
I also have a drop rake I will be attempting to pull through pond to see if I can clean some debris from bottom.
Am I nuts or just delusional?
