I don't think horse manure is much of a problem. Not as versus cow or chicken manure.

A horse has a very inefficient digestive tract. Look at some dried horse droppings. They are mostly compressed grass. Unlike a cow, it doesn't get brought back up and rechewed.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
