dead fish

[carmel]

i am so upset...yesterday we pulled the leaf net off the top of the pond and reset the pond bubbler...everything seemed to be fine..we could see a couple fish (koi) down low....today i went out to find 2 dead and two more near the top, its cold here...around 0 celcius and we have some snow. they shouldnt be up swimming around should they?? and what would have caused the deaths?? us taking the leaf net off maybe?? i lost all them last year because we have a flash freeze and i dint have the bubbler in in time....

Hi carmel,
We need to know details about your pond setup, size, filtration, maintenance routine, numerical water test results and stocking levels first.

So sorry you lost your fish
I doubt the cold is to blame, something is obviously going on with your setting so please listen to @MitchM , give all the info necessary so he/others can help you figure out what the problem is, and you can stop losing fish

You're right Gemma, cold is not a problem with goldfish or koi, it's usually a different water quality parameter.

I should correct that.
It is always a different water parameter.
Goldfish and koi do not perish from cold water temperatures.

HI...its a 2000 gallon pond, sicce 40 with ultra violet lite. i used pond balance in the summer and no issues with algea, backwashed every other week. all seemed fine until we disturbed the fish by pulling the leaf cover off and the water sloshed around, it was the next day i found the fish.
