How long does it take koi eggs to hatch?

Phyllis and I tried putting a blue filter mat in the pond when we began
to see foam by the streams. Thought it might reflect koi spawning.
Turns out to be right! Eggs on the mat. Moved them to our new 400 gal
berm veggie filter.

Does anyone know how long it takes them to hatch?
=========================================
It was a warm spell when my koi spawned. It took less than a week for them
to hatch.
I have hundreds of koi fry in 1/2 barrels and 150 gallon kiddy pools.
