I always advise caution re fertilizing a pond. If you need it, go ahead. However, if you overdo it, you can kill fish. Been there, done that and the bigger fish go first.

It's kinda like tequila.

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.

Without a sense of urgency, Nothing ever gets done.

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
