Gary, That brings up something I've always wanted to know, how long do you
think that the power could be out for till your fish are in danger? I have a
750 - 800 gallon pond and 10 Koi. I always worry about that every time we
have a big storm here in Arizona. Thanks Kc

OK, Take out the filtration factor and what is too much for koi?

The reason I ask is that I see so many different claims, and then I go
see a koi breeder and they have 20 big ones in 1000 gallons (30+
inches). And 50 or more in 750 gallon setups...

The main reason is, like others said, fast turnover. Those fish are not
crowded in that tank for that long. And they filter the heck out of it.
The latter point also equals risk. If they had a power failure for
an hour or two probably all those fish would be dead. They probably
have battery backup, since they know this. Do you? Lower stocking
rates means that the filtering can fail for a longer amount of time
before it's terminal.
