Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Seine for removing algae?

That's a good idea. I would take that idea a step further. If you are going to use that multiple times a year, you have to think about storage. A seine works by the top of it floating on the surface, and the bottom either dragging on the bottom or hanging down in the water column like a shower curtain. There is a rope on the top of it and a rope on the bottom of it to pull it through the water in the pond.

The snow fence is a good idea but it will need modifying.

If you are concentrating on the floating algae, cut that fence so it's only 2' tall. Thread a Polypropylene rope through the top of the seine. I say thread because if you zip tie it to the rope you have to rely on the strength of the zip ties to hold the net to the rope. Polypropylene rope because it floats. You will also have to either thread the rope through floats or find a way to clip floats to the rope to keep that end of the seine floating. Floats

You will have to weigh the bottom of the net so it is vertical in the water column. Again use a rope on the bottom, but this time I'd use a braided nylon rope. You will have to weigh the bottom rope. Enough weight to get it to sink, not too much weight so it sinks the whole thing including the floats. Net Leads Or you could use a weighted rope like this: Weighted rope

I would extend the rope anywhere from a few feet to 30+ feet from the end of the netting. That will give you something to hold onto when you put it into the pond, and pull it to the shore. You want to pull the bottom of the net slightly ahead of the top of the net so it doesn't ride up and over the FA.

Encircle the FA mats. Pull to shore, use a rake to get them out of the pond. They may be too heavy to pull out of the pond with the snow fence seine.

Or if that sounds like too much work to build it, call a net company like Memphis, Nichols, etc. to have them make you a strong short seine. I'd think you would want mesh that was 3/4"-1" . Get it coated as the new will last a LOT longer. You will have to lay it out on the grass to dry before rolling it up and putting it away or it will rot. You won't have that problem with the snow fence.
