Whenever I'm asked to diagnose a problem or explain unusual behaviour, I invariably give this advice:
Water parameters are the first thing to check because bad parameters can cause health problems directly or weaken the immune system so that a fish succumbs to a parasite or pathogen it could otherwise have resisted. Even if poor water quality doesn't play a part in initiating a health issue, koi have a much better chance of recovering in good water than in bad.
The minimum parameters you should check are pH, ammonia and nitrite. Nitrate and KH can also give valuable information to help interpret the other parameters.
If any water parameter is incorrect then it should be brought to an acceptable value as quickly as possible so as not to unnecessarily delay any medical treatment that may subsequently be needed.
Once suboptimal water has been ruled out as the cause then the correct procedure is to scrape in order to identify if any parasites are present and choose the appropriate treatment. This is the best approach for the health of the fish rather than the hit and miss approach of trying a selection of different cures.
If you could give those values, along with the pond temperature, and say if you’ve recently added a pond treatment or medication, it would be helpful to determine whether the problem has been caused by incorrect or varying water parameters, or some other cause. It would be especially helpful if you could give two pH values; as soon as you can after daybreak and again soon after dusk.
In the meantime, you should stop feeding and do a 20% water change with a dechlorinator. That won't cure the problem but if your water parameters are out of the acceptable range, it may do some good and certainly wouldn't do any harm.

Your pH is a little high but that won't be the cause and, with those parameters, the temperature isn't too important at the moment.
This is likely to be parasite related so what you now need is to scrape that koi and a few others to determine which parasite, if any, is present in order to choose the correct treatment.
I've just been called for dinner so I won't be able to respond tonight but there are others on here who can help you with that if you need it.
Gotta go, been called twice and I'd like to eat my dinner instead of wearing it!!!!

This is a simple go-no go test that will tell you if you have chlorine or chloramine in the pond water if you use manual dechlorination or coming out of the dechlorinator unit if you use one.

I’ve just purchased a big blue, but when I filled the pond I used a small dechlorinater
could chlorine cause a skin complaint like that?Last edited by Ollykoi; 03-09-2020 at 09:21 AM.

It's one possibility if the cartridge was exhausted or you were running water through it too quickly for it to remove all the chlorine/chloramine but you would expect more than a single koi to have a milky skin if there was chlorine in the water. So you should still scrape that koi (and a few others) to see what, if any, parasites are present and test the water for chlorine to be sure.

Ok thanks, I bought a novex led jr but I can’t seem to see anything on x40 works fine on x10 but can’t see close enough, Wish I spent more now, I might have to sell this on and buy a better scope

In a word "no". Carp pox looks like white or pinky white blobs of candle wax on the skin as shown in the pictures of typically infected koi in this article on my website;

He has significant very reddened/inflamed areas on him, so yeah is not at all consistent with carp pox.
Something irritating him in the water is likely, or failing that a parasite issue but you describe this as being very acute in onset.2016 new 6000 gallon pond

Also when blowing photo up. You can see bone on the dorsal fin. So the fin has a problem.
So could be finrot. Agree with syd and feline. Not pox. You need it microscopeing.
Put your address up on here and maybe some one who lives locally can help. So my
Take is it could be bacterial problems. Causing finrot and mouth problems.

I personally have never seen this before (possibly seen similar but only in small patches) and whilst the guys who've posted above are very knowledgeable, experienced and have approached a potential diagnosis the correct way, this could be a condition unique to that fish as opposed to an ongoing water or parasite problem, although it is true that those problems can be the trigger for something like this.
So here are some other considerations:
Firstly is the Koi eating well and swimming normally and have their been any behavioural changes since you've had it?
Definitely check chlorine, different koi can react differently to its presence and skin irritation of various forms isn't uncommon.
Have you had elevated ammonia levels at any time since this Koi was in the pond and if so how high did they get?
Have you had elevated nitrite levels at any time since this Koi was in the pond and if so how high did they get?
Scrape it and look under microscope, check for parasites in the scrape first and if none present compare what you see with pictures of fungal or viral scrapes online. It has a fungal look about it (and viral infections can cause similar weird skin complaints) but I'm at a loss to say if it is fungus as it doesn't look like the common saprolegnia or fungus of similar genera.
Were there any signs of this when you got the Koi, and how long ago did you buy the Koi?
Do you know if the patches are on areas where the Koi was previously red and has it lost any red colouration since you've had it?
Do you have any non-standard products or sealants in contact with the water?

This looks like what happened to my ai goromo. I lost it In the end unfortunately.Most the red in the fish went like that with a sort of white glaze over it and when I cleaned it up it seemed like a massive open wound.

Hi so I put said fish in a separate tank and it seems to be clearing up, I did add a bit of fmg so not sure if that helped...

New pond and fish issues
What was the outcome for this fish?
Lots of questions were asked would be good to know if it recovered and if there has been any reoccurring issues.
