Getting rid of moss on farm ponds

[yogio]

Grass carp won't eat filamentous algae, which is what pond moss really is. The best product is cutrine + (sold at Southern States at approx. $22/gallon). Copper sulfate works basically the same way, but is potentially toxic if overused, especially at higher ph levels. Cutrine also comes in a granular which works better on bottom growth, but is steeper in price. Aqua Shade is pretty, but in my experience DOES NOT prevent algae. I also have a diffusing aerator, which prevents thermaclines and "pond turnover", but has not prevented algae growth. You have to be careful with really heavy growth, because if you kill it all at once, you will get oxygen deprivation and a fish kill. My pond is about 1 acre/ 15 foot deep at the deepest (only about 9 now with this **** drought). We fish and swim in the pond and water visibility, even with AquaShade is about 5 foot. I continously have to fight the algae around the perimeter of the pond and in 2 bays that are shallower than the rest.

They will eat filamentous algae or at least they have controlled it in my pond.
