Super - this is all helpful.

On the koi question. As this is my first pond - where I bought the fish to stock - the guy was really after me to do that - because of the algae. The pond gets water from runoff and a small pump that can dump app 500 gal/day into it - so some concern I would get algae w/o a true inlet outlet and flow - so far btw that has not happened.

So...if algae is not a significant amount of their diet - what is? They have more than doubled in size from July to now.

Did I makle an error putting them in there to begin with?


This is all very helpful - thank you!
