Pond disaster

me Dad woke me up this morning about 6ish only to find all my fish in my pond to be floating on top of the pond.

some of the koi carp in the pond where about 2lb, all me shubunkins, golden aufs the lots gone......left with 1 or 2 goldfish.
1 of me biggest koi is in a bucket and i have ben trying to revive it but no result :(

some £££ lost there then.

also over the weekend one of me heaters when off in me 6ft tank and i lost a few of me tropical fish, neons,angel fish, plattys, newts...all gone......what a bad week. :( :( :(
 
the koi i had in the buket i managed to get some oxygen into it......it was lying in the bottom for 3 hours on its side....

i thought the swim bladder would have defianlty gone on it. Went to shields to pick a new pump up and when i got back it was swimming in the bucket fine after 5 hours out of the pond.

It is back in te pond now as i cleaned it all out ....how long it last for i cant say.....but it seems ok.
 
jonny did you check your water parameters before you cleaned out the pond ?unusual for all the fish to die due to the heat ,koi and orfs can tolerate a massive changes in temp as long as its gradual ,id suspect foul play myself m8

considering it happend overnight,the water would have heated gradualy and wouldnt account for so many deaths at once
 
well you live and learn something new every day, but remember a couple of degrees change in sea temp over the last thousand years has forced all the cod north. A couple of degrees maybe more over night quite a change, my mate who kept and prodably still does for years, always used to leave new ones suspended in a bag for a day in the watre they came in to acclimatise to their new surroundings.
 
Johnny heres another thought, is it the same water that is circulating all the time. Could be that with the temp being so high the water could have warmed up and i hate to say it, it could of partially cooked your fish. Tepid water is enough to cook a bit of fish meat, wouldnt recomment eating fish meat cooked in tepid water though, dosnt kill the worms
 
alan i turn my pumps off over night tho....so it wasnt circulating.....i just do it so its less noise for my neighbours. So that guess is out the question. I think its the lack of oxygen in the water due to the humid weather....as the rest of the surviving fish were at the top gasping.

it may be your pond is overstocked and there wasnt enough oxygen to go round after switching off the pumps.just a thought.i presume it is an established set up with oxyginaters etc and a deep part for hotter weather.
 
what i was getting at Johny is that if the pump was off the water would not have cooled down from the heat of the day. Does not take much sunlight to warm water up. when i take thew young uns to the beach early morning around 9am, the water in one of the pools on the beach about 50 yards long, 10 yards wide and a foot deep in freezing just after the tide goes out, within half an hour of the early morning sunshine it is nice and warm. When we leave around 10.45pm, it is very warm. Imagine the temp of the watre after a whole days sunshine. It also depends on how big your pond is as to how much the watre heats up. Do you keep a thermostat in it to keep an eye on the temp so you can do somthing about it, fresh water, when the temp gets to much.
 
bugger the neighbours lol ,the 2 either side of me like the sound of running water during the night ,you could try a pump jonny with an airstone attached ,not too noisy,ive had no problems with my fish with the temp topping high 70s,how deeps the pond , if its shallow the fish wouldnt have been able to bottom rest in the cooler water
 
Got a pond in the garden, filled with small fish + 1 tench (God I want to catch it every time I see it as it is the pollock of the bunch) and we\'ve been away for the weekend and it\'s been much hotter here than at Jonnys..... and they\'re all fine. Even when the water goes off, as it does, they seem fine. Not an expert so no more help I\'m afraid.
 
johnny it sounds like over crowding to me, also if your switching your pump off over night you are destroying the bio filter cos it needs to be running constant for nature to help the process bof cleaning the water. i run mine from when the water gets to about 50 degrees till the end of autumn or the hard frosts come.
 
sorry to here about the fish jonny, my pond has approx 3000 gallons of water and the pump is never turned off, likewise the 2 big air pumps are allways on, the main problem with turning off the pump is that with no flowing water the filtration microbes are damaged likewise no oxygen is entering the water as previously said...over stocking at this stage will become obvious as all the fish struggle for the small amount of available oxygen...some of the fish in my pond probally wiegh 15lb each, especially the 2 ghost carp, the koi are probally about 7lb each.
my favorite is the sturgeon, its about 18 inches long and you can lift it out of the water and stroke it...
