Thank you to you both. I have some nitrite out stuff, and have used it. But my level is still 1.0 :twisted: I have done another major water drop and am just hoping for the best. Haven’t given any food today, and won’t tomorrow until it drops.

I have put up a picture here to see if anyone recognises what is actually wrong with my koi. Her swelling has gone down a bit. But the left hand side is still a lot more massive than it should be. Is this for some reason. Infection? Liver problems? I just don’t know I would like to know more about it, and perhaps why the swell up, is it like water retention?

The second picture is of my chagoi, with the furry face, you can just make out the grey blobs? Again any thought?

Anyway they all are pretty active so still keeping my fingers crossed for them.


It is always the way, I am dropping water to clear up the nitrite and adding the right bacteria stuff. There is nothing I can do at this time of night, I can’t buy stuff from somewhere that isn’t open. Or when I don’t have a credit card.

I know my fish are stressed, but I am trying my best to reduce it. Speak soon.


Oh and just at the right time, my ph testing kit has run out. Everything always happens at once doesn’t it . Damned.

All but the sick one ate this morning, I think she still isn’t happy. Also I think my hawaki (sorry for the spelling) has some fin rot! Will take a closer look later when I get home. Poor things have really been through the mill this week.


I tested water when I got home and nitrite is high so am doing a %50 drop and filling with fresh water, also going to add some bacteria regardless to the filter to help it along. Will have to wait and see what the results are. I am sure my little chagoi has fluff all over his face too, so there is a bacterial infection going on there somewhere. I def need to clear that up any ideas whats the best thing? I am going to catch both fish when Paul gets home. I have an anti bacterial powder stuff which I can bathe them in. Will do that and rub some Koi cream on the yellow ones sore. That will help her along.

Other than that I was thinking about Salt but I really want to wait till I have had the test results before I do that just to make sure everything has gone.

Keep you updated


I’ll try and get a picture later when Paul is home. I cant catch them they move to quick for me. He does have a couple of bumps on him, which dont look great, but this was the fish we had problems with in the winter, and he was starting to heal nicely. Now he’s all poorly looking again.

Will put some pics up for sure.


I’ve watched my fish as the pond is refilling, and I have seen three of them flicking still :cry: Could there be something else in there that is causing this ? Or might it be just that the nitrite level is a little high. I have done a 50 water change, I just really really don’t want anything else wrong. I don’t think I can cope if they all end up with sores and stuff.

My yamabuki is swimming around properly now, her fins aren’t clamped anymore, and they all ate before. Am I just panicking over nothing or should I be still concerned?

Just worried over my little wet friends.

Hey all,

Well the Nexus is purged, and with the fish still flicking I am going ahead with one more try with pp. This should stay pink for the alloted time. I was also advised to slightly up the dose and put it in almost in one go.

I am not looking forward to the next few hours, but am hoping that all fish will feel much better once the critter is dead. A scrape is going to be done and then I am going to have to treat for a few sores, my yamabuki has a little red spot developing and he has one fin clamped this morning. Moby however the first to show signs is still swimming around a lot and looks still bothered but her fins aren’t clamped and she isn’t hoovering as much.

Will let you know in an hour or so how I am doing.

I will need all the help I can get to get these poor fish through the next weeks or so, recovery takes time.

Thanks for all the help guys.



One hour twenty mins later….

Ok so pp has been in over an hour, so far no bad reactions. Even with the sturgeon…. although she is swimming around on the top shelf, nothing unusual. She isn’t floating like she was the other day when we had to nurse her in the oxygen bubbles.

I have taken most of the air off the nexus though and am circulating it into the pond which I didn’t do the other day. So there is an extra air stone going full gallop as well as the pipe and smaller air stone. I have seen two fish bob up once for air, but no one is gasping at the surface. They all swam around rather quickly for about 10 minutes when it first went in, but they have settled down now and when I went over the chagois came up for food, lol. So fingers crossed I am almost there.

If it can keep like this for another few hours, I will be happy. And hopefully Trich will be all dead… At least then I can start to feed some more again as last night after 12pm the sturgeon were rather active and searching for food. Bless them they will be really hungry, and its not fair on them not to feed for much longer.



At present the pp is holding strong, and all fish are ok and active when I go near them they come over. So Its 3 hours now which is good. I am watching them very carefully and helping my mum wallpaper our bathroom. Its keeping me from going insane over the fish.

I will def dose with your suggestion, and also start to put other things in regularly to help all the fish.

Update you later in another hour or so.

Cheers without this forum I think I would have been turning to the bottle to keep me sane.



Ok, so it turned orange after 4 hours 40 minutes. I am hoping that is enough to kill the trich, fish look a little stressed but are still swimming about enough and haven’t been gasping or doing anything weird.

Let you know later how they are,



All fish alive and well… So far so good.

I am in work for the first day tomorrow, so I will be thinking of my poor fishes all alone with no one to watch over them…. :cry: Hopefully they will be fine. I am going to give them a little food later and then in the morning. Testing all water parameter’s first….

Will email you in the morning.

I might try and give them a little bit of food. But not too much, I want to dose tomorrow hopefully for the last time with pp. I am hoping with all the cleaning etc that it will stay active for at least the 8 hours. If not I will settle for at least four. I am going to stick to the recommended dose, although I have been advised to put it in all in one go over the surface of the pond, so we will see.
I only have K1 in the filter, but there was a bag of oyster shells in there that smelt terrible when I pulled it out hence why i looked to the bottom, and realised it needed doing. So its now on my cleaning rota, I will have to do it more often. At least the hoover helped a lot.

Just checking on them before I have a kip, I am exhausted with all the worry etc, and I am working late tonight.

Catch you later hun, and thanks again.


Update, all fish except for the sick one ate, sturgeon very hungry although I can’t put too much in. Let you know how it fairs tomorrow.

so this morning, I think I spent emptying my nexus, and cleaning the bottom. It took me ages to get all the k1 out first then at least I could see where I was hoovering. I think a reason why my pond was so bad is because there was loads of gunk in the outer chamber. I am sure this shouldn’t happen? Anyway, I will put this into my cleaning routine, and perhaps every few months completley drain it off and hoover the bottom.

My sickest fish is a lot happier she is swimming around a lot and when all the fish came over begging for food, she came to. Fingers crossed that things are getting better.

I have still seen two of my fish flicking so I do still think that tric is there. I def don’t think the pp was active for long enough and I am hoping that if I do redose tomorrow that this will be the last time. I really could do with another scrape doing but everyone is so busy. So I am watching the koi before I go to work and I am going to see how it fairs in the morning. They have had over a %75 percent water change in the last four days, so I guess we shall just see.

I’m not around any corner yet, but here is hoping.

Oh and ps, how long can koi go without food? I haven’t fed them in 3 days. And my sturgeon are pretty annoyed, I don’t kow how long they can do without, but I do know they suffer from malnutrition before the koi. Any one any ideas?

I am working later, but will keep you all updated.
