3 koi died in my pond in one day?
Answers:
Did you add any water? Did you put any chemicals in it? If any kids, did they do anything to it? Are your fences locked?
Many possiblities.. I have a pond too.
EDIT:
AFTER READING YOUR ADDITIONAL INFO
So it rained alot that day?
Possibilities are many
The rain could be polluted. Was it warm that day? Sometimes warm weather can reduce oxygen. Too much rain can also sharply change the pH, so that is also a possibility. I would get the water checked. If you don't have any checking stuff, I would take a small cup or bag of water to the pet store and have them see.
Could it be anything to do with a lack of oxygen in the pond? Go to your local fish centre and see if they have any aerating plants to add?
How old is the pond? How big were the fish? Did you just add them? Did it just rain? Have you checked your water? Please give some more info! Thanks!

With koi it's usually down to poor filtration and/or poor oxygenation. When mine died, it was usually at the end of winter when there was probably a build up of noxious gases from dying vegetation.
Mine did too all in one night, 5 kois, and 12 goldfish. Stolen?perhaps. An animal visitor? Before these guys I lost 2 other koi but never a trace of them.
It's a suicide cult thing with Japanese koi called 'Ari-koi-e'
Might be something in the water or something that only the koi are allergic to. Test the water to make sure nothing more can go wrong. Ask someone about the food you are feeding your fish, so nothing can go wrong.
Yes the deaths were caused by you pisssing in the pool.
I am not a fish expert but you say you have chubb in your pond, where and when did you get them from. There is a possibility if you got the chubb from a river etc that they have infected your pond, it's only a guess as I had a similar problem.
Hope this helps.

this are some of the reasons I can think of:
1. they could have been infected with disease along time ago.
2. sudden change in their environment, the rain perhaps, has stress like sudden change in temperature, increase in water acidity, or any other factors that were not favorable to their living condition that leads to their death.
3. water could have been polluted that the Koi were not strong enough to tolerate the pollution.
its lack of oxygen.solution is to get a small bail of hay and place it next to the pond that puts oxygen back into the water
I have a rather large fish tank in my room & I bought some Koi & everyone on here told me that they were going to die because of lack of oxygen & because they were too big for a tank . But that was at least 2 months ago I believe & they are all still alive
Hm ; I'm not a big fish person but if you just put them in there maybe they went into shock because of the water temp. change or maybe there was something in the water that killed them. Who knows - it might have even been that one of the fish was sick - Not sure good luck with the next batch though.
I don't know where you live but the same thing just happened to a bunch of my friend's koi a few weeks ago. She is gonna take a sample of the water to a pet shop. Not all pet shops do that but you could call in advance and see.
if it was humid the koi could have suffered lack of oxygen,plants aren't really any good as koi will eat them,you should always oxygenate the water with an air pump..also check the water quality for ammonia and nitrate levels,you may need to do a part water change.a good way of knowing if there is a lack of oxygen in the water is to put some orfe in,a lot of peps keep orfe as they do not tolerate poor oxygen levels,so you would visibly see if the orfe were in trouble you need more air,only thing is orfe can make koi skittish as they dart about.small water changes will help reduce toxins in the water,if your fish are flashing,ie rubbing against objects or flicking against the bottom of the pond,this also usually means poor water conditions or parasites,buying a bag of pond salt will help kill any parasites and also acts a a destresser.if you do do a water change it is always best to buy tap safe, as it takes the chlorine out of the water
,oxygen level low in water because of hot weather
Firstly, my sympathies. It's always sad when pets die. :(
There are many possible explanations for your fish dying.
In my experience as a fishkeeper, water quality is a frequent culprit of fish death, especially with koi and goldfish who are very sensitve to any lack of oxygen.
You can buy water quality testing kits for tanks and ponds, your local aquatic supplier would be able to advise you about those. Or maybe even test a sample of water. They should also advise you about the process of changing the water and getting a good chemical/bacteria balance back.
Heavy rain could have washed a contaminant into the water - (perhaps you've used some pesticides or plant food or something in the garden) theres probably not much you could do about that, rain happens.
If there are any water quality issues (as opposed to a koi-specific disease) the chub might be showing some signs of distress, too. Even if they dont seem obviously sick you might want to keep a check on their behaviour.
I wouldn't advise adding any new fish until you can be sure it wasnt the environment which killed the others. Good luck, though.
when storms move in the barometric pressure drops and I believe the oxygen level is directly affected by this
also does your pond receive any runoff water from your roof?
some shingles are highly poisonous
do you have filtration/oxygen in your pond?
did your koi have any kinds of marks on them?
Oh My God the fish got fried
