They have been in the pond for 2 nights now, they seem to be doin well and ate twice today.
I have three koi in the 4-6inches range, my pond is 1600 gallon in size.
I checked the salt level, ph, nitrate, etc. beforehand all good.
Thanks Joe for putting your personal input...I was sweating it the last 48 hrs

I'm glad someone else admitted having done the same thing
dan, thanks for putting things in perspective.
