Hello, all. For various reasons I haven't posted here in well over a year.
My pond and stream are doing very well as are my koi. I have 11 koi. Eight
of them are now 12" or longer and it's getting really expensive to feed
them. (I'd like to stop feeding altogether and let them make-do with the
algae & gunk in the pond but my wife insists on feeding them daily).

Can anyone suggest something really inexpensive to feed them?

Thanks, Gary
