White patch on fish, advice please.
One of my fish has a patch on it, sort of milky colour, please see photo.

Someone suggested to me that I should put salt in the water. I have some Dried Vacuum Salt. I should add that I am new to looking after our koi pond since my husband died 6 months ago.
I started googling about quantities of salt to add, and then I got apprehensive because of mixed comments about the use of salt, and that once added it takes an age to get shot of, and that koi are freshwater fish. I found a chart giving quantities but I don't know what percentage to go for, or if I should salt at all. The pond is full capacity of 3000 gallons, 13600 ltrs. so I was going to use 2500 gallons.
I would welcome any comments please.
I have an Evolution Aqua 310 Filter unit.

Hi there. Sorry to hear of your husband passing away. So sad. I can t see very well with that photo. Could be mucus build up. First thing we normally ask
Is water parameters. Ammonia nitrite ph
Kh nitrate. Then a scrape of the fish. If you put up where your location is maybe someone can come and help. Who lives locally. Someone has done that and been sorted out.
Rather then salt the pond. You could do a salt dip in a bowl.
Reason not to salt the pond is it takes a long time to get the salt out of the water.
And some treatments you cannot use with salt.
That's why people salt dip.
Here is a link for salt dipping
https://www.healthykoi.co.uk/koi-hea...nts-salt-dips/
Copied and pasted from the link
Add salt at the rate of 3 ounces per gallon of water and mix well. Insert an air stone into the water. Carefully place the Koi into the saline solution and leave in the dip for between 10 to 20 minutes, depending upon how the fish copes with the treatment. Should gill disease be suspected, use a far weaker solution (1.5oz @ 10 mins).
Should the Koi become very stressed or go on its side and stay in this position (usually indicating a respiratory problem), it should be removed from the dip and returned to the second bowl containing the un-medicated water.
Hope this helps fred

Fred, Thank you for your help. I could not think that putting Kilos of salt in the pond was right. I disposed of an old water testing kit and had been visiting my local World of Water for testing as they explained the results which is helpful. Due to lockdown have not been able to go so yesterday I ordered a Kit from Amazon. The last test was at the end of January and all the counts were alright then.I will try doing the salt dip this weekend. I have a couple of plastic garden bins which I could use. How soon would I expect to see any change?
I will get back to you after I have done the water test.
Thank you Cynthia

Might be worth saying where you are in case someone is close and can help out

The thing is where being blind here. It's all guess work. So we don t know what is causing the problem. The fish really need scraping and micro scoping. Plus water everything tested. Chlorine. Ph ammonia
Nitrite nitrates kh.
It could have knocked its self. And that's causing the grey patches.
As said your better off putting your location and some one will pop round.
Using social distancing.
I just wished you lived near myself. I would
Come and help.
Try the salt dip. And see if it helps.
And inspect the fish to see if there are any
Wounds. Under the fungus. Plus a damaged scales. As for time scale. That depends what is wrong. Which we don t
Know. The salt dip may help. We might get lucky.
Fred

I have managed to give two koi the salt bath last Saturday, and I think the smaller one has responded a bit. Here are 2 photos I took whilst they were out of the. pond. the larger koi has whatever it is on its tail and near its fins too. I cannot seem to get the photos to upload!I have received the water test kit and tested this evening. Nitrates are high.
PH 7.6
NO3 100
NO2 1
GH 8
KH 6
CL 0.... Photos just arrived.
I know it says to change water but this is a 3000 gallon pond, I did top it up yesterday. I see you can buy stuff to clear the Nitrates without changing the water, do you have any recommendations please?

Here is another photo of something on the side of the larger koi.

I have joined a Wiltshire Koi Facebook Group, so maybe I can find someone to help me there.
If someone has ideas about a product to remove the
nitratesI can get it ordered quickly.
Thank you for helping, I really appreciate it.

Hello,
To my untrained eye, it looks like carp pox. I have one at the moment with it which I would expect to clear up as temperatures increase.
I am in Swindon if you want me to come and have a look.
Cheers,
Andy

Andy, I’ve just had a quick Google and I think you may be right. I’ll read up on it in the morning. With lockdown I suppose I ought to wait a while before inviting you round. I did see that it is not treatable and as you say may improve as the weather gets warmer, which maybe why I thought I could see an improvement after the salt bath, it is more likely to be the weather getting warmer this week than the salt soak.Have you any suggestion for the high nitrates?
Thank you for writing.

Hello Cynthia,
Initially I would suggest trying to do a partial water change.
Personally I have not used any treatments for high nitrate so would not be able to give you a very informed opinion. I am sure others would be able to help with that.
Cheers,
Andy

The Tetra test kit registered Nitrates at 100 on their scale, so I don't know if that is 1 something or 10 whatevers. It does not says. I decided to check the house water supply and that registers 50 on theTetra scale, so I'm thinking the water change won't actually be much help. I think I may have been feeding too much because the water was OK during the cold months when I was not feeding at all. I read that over feeding adds to nitrates too, I did know not to overfeed, and I am only doing once a day, I just have to learn as I go along.
I do think the white candle wax type looking stuff on 2 of the fish is koi pox. It seems to have come off the smaller one a bit, maybe the warmer weather/water.

I have ordered some Envii Nitrate Klear, will report back eventually. Am wondering whether to put a plant in the pond, need to find out the problems with doing this.

I had a small surge of koi pox on a couple of my fish. My local dealer (koi) advised me to squeeze some fresh orange juice into a cup of food and feed. It seems to have helped as its pretty much cleared up after about 3 doses.
