Koi eggs are clear to white in color so no they were not koi eggs.. sorry.. not sure if they are eggs from the other fish but for sure not koi..

6 days ago I lost all 5 of my beautiful koi because someone left a garden hose running into the 600 gallon water garden for over 4 hours. When I discovered what happened I immediately added a chlorine neutralizer and tried to change out some of the water but it was too late and all the fish were lost. Later in the day I noticed there were fish eggs all over the pond and in the last couple of days I have seen some newly hatched fry. Since the female that died was very dear and special to me I want to do everything possible to ensure the survival of as many of her offspring as possible. It now seems obvious that the fish spawned just before the water was added to the pond so my question is do you think the chlorine could have harmed the eggs?
Also, I am just noticing that there are some accumulations of white eggs (they look like large granules of salt). Are these unfertilized eggs or something else??? How many days does it take for the eggs to hatch? Any advice as to how to care for the fry that have hatched would be greatly appreciated.
