but this is not about how we would feel....this is what is the least risk to the koi. no food for additional weeks at 50F poses what risk? surely not one from TAN in the pond ....
I stopped feeding Jan 1. Our pond has been between 50F and 57F during January (so very glad I got a solar pool cover!) with air domes and Nexus churning away. If koi are hungry, they have algae on pond walls. Today is first possible day for them to get WG pellets. And since we are have a sleet festival today

that ain't gonna happen. They will be just fine right though all of Feb without pellets if cold temps continue. No pellets until water maintains 55F and no cold front is headed our way.
Tough love!!!
