Young carp dying.. New pond #1
Hi I recently upgraded to a new pond for our fish and added medifin and tetra aquasafe to offset any issues that may arise due to the move. All seemed well but just less than a week after the pond move (last Sunday) and one of the fish really does seem in trouble. There are four carp three small youngsters we got last August and one older carp 11 years old. It's one of the youngsters that is in trouble.
He keeps rolling on his back and is swimming past and even through the food I put out- no interest. Seems to be gulping as if eager for food but I'm guessing he is gulping trying to breathe?
The other fish seem ok but I do wonder.. the food I put out has gone each time I put it in the pond. Yet they have not rushed to their food at all this week..
I have a pump and filter ready to go in there ASAP (family emergency prevented me putting it in sooner) but is there anything else I can do to help?

Re: Young carp dying.. New pond #2
Do you have a test kit? If so please test and post results for ammonia, nitrite and nitrate. I strongly suspect that the problem is a lack of filtration. However, if your filter is brand new it won't solve the problem immediately as it takes time for it to cycle and deal with the ammonia fish produce - 6 weeks or so. In the meantime, partial water changes will help as will double dosing with this every 48 hours: https://www.ebay.co.uk/itm/Seachem-Pon ... ec32a7:g:GggAAOSwDApacGuT

Re: Young carp dying.. New pond #3
Thanks for the reply sadly the little fish is nearly gone.Gulping but seems to be losing his orange colour and barely moving.I don't think it's the water as all the fish really have seemed ok till this afternoon and this seems to have happened and killed him in less than half a day.As said above only thing different this week is the youngsters did not scamper to their food as they did in the old pond but I was not worried as they were active and the food was soon gone.

I will try a water replacement tomorrow and the pump/filter was added tonight.I expect the poor thing to be gone by morning and it's about saving the other fish now.

Re: Young carp dying.. New pond #5
The little fish was found dead this morning poor thing..will be filling in where the old pond was later and he will be going there.
All seems ok with the other fish.. still not in a hurry for their food though.

Re: Young carp dying.. New pond #6
Sorry to read that the little fish has died.

Glad the Seachem Pond Prime and a test kit is en route - hopefully those, and following Fishlady's advice, will help get the situation under control to prevent any other fish succumbing while the new filter goes through its cycling process.

Re: Young carp dying.. New pond #7
We lost the little orange carp yesterday.. started rolling on his back and side just before lunch and was gone and buried by 5pm.
Got the remaining two out and did a complete empty and clean of the pond. If I'm reading it right the test strips are showing water is OK?

Only the test strips have arrived.. still waiting for the other treatment.

Re: Young carp dying.. New pond #8
Not sure which of those refers to what parameter as I don't use strips. Can you post the results comparison please? Also, I don't think those strips include an ammonia test which is what you're currently most likely to have issues with.

Re: Young carp dying.. New pond #9
Hope the photos help.. Done just now..

I think I might have found the issue.. my sister reminded me that in the old pond they had a stone bridge the fish liked to hide under. She suggested maybe the fish died of stress due to having nowhere to hide.Also this new pond is right by the kitchen so more general activity than the old pond at the bottom of the garden. So maybe the shelter was important?
Sure enough I have set the remaining two up with a cover over a quarter of the pond and they were in there right away. A few days have passed and all still seems ok. Swimming round before returning to shelter. Pond has a combination of of pond prime/aqua safe and medifin. Hopefully all will continue to be well. :)

Edit.. The photos did not load so reposting - the test strip has dried but hopefully gives an idea (taken about 30 mins ago)

Re: Young carp dying.. New pond #10
The lack of cover might at least partially account for the problem - it will certainly be a help having a cover on.

However, the filter is most likely going through its cycling process, in which case you should follow Fishlady's advice as per earlier in this thread.

I would also advise getting an ammonia test as it will be crucial to keep an eye on this both during the filter's cycling and regularly in the future - if there is ever a sign of fish being unwell or acting strangely, the first 'port of call' ought to be to check the ammonia, nitrate and nitrite levels, and rectify accordingly as almost all problems are accountable for by an anomaly in one or more of these levels.
