Temperature Changes

[number20121]

I am just wondering in general when people have goldfish or koi ponds, isn't there a lot of temperature fluctuation going on? Even a big pond will warm up fast and a lot when the sun burns down at it for hours.

I'm in a very temperate climate in So.Cal.,and there's generally not much flux in the temp-but I def add a heater in the winterI am forever grateful that I don't have to deal w/ moving my fish in winter and summer

The single tails and koi are able to deal with temperature drops more easily, and since there is more water it takes longer for the water to cool down. That's why in the winter it never completely freezes all the way. I won't go into details, Too many sciency words about water and chemistry.

But say in early summer when the nights are cooler, and then within a few hours the sun rises, shines right on the pond and the temperature in it goes sky rocketing.

So you have a patio pond of 150 gallons, out in the sun. This is going to get hot FAST. And some people don't just keep single tails in them, but fancier fish.
