i recently did a complete water change in my outdoor koi pond due to
algae take over and all koi have died within 24 hours, why? and what
can i do to get it ready for more fish to be stable?

Hi! Please move to rec.ponds.moderated as this group has been abandoned due
to trolls.

A complete water change was too much of a "shock" if the water temperature,
hardness and PH varied greatly. You need to acclimate them when doing such
a major water change. I use 150g kiddy pools from Wal*Mart to do that when
we drain down and clean our ponds. Over an 8 to 10 hour period (it varies)
I add more and more of the "new" water.... then return them to the clean
pond.

Did you add enough dechlorinaror to the water before returning them?
