E Mail received today:

Good Day,

I need help. Seems my koi's are sick, but not all of them. I think it might be fin rot, but not sure. I'm sending pics with, if you can help or point me or point me into a direction.

I did buy medicine from petshop for fin rot, I use salt in the water. Water is clean with plants in. Enough movement of water and air.

Thanx

Abri

Abri

The first Koi on your picture had a severe case of Aeromonas bacterial infection which resulted in lifting of the scales and indicates severe Dropsy, normally resulting in death due to kidney failure.

The other fish also suffered from the same bacteria indicated normally by the mouth that rotted away, also known as "hole disease" or "Ulcers"

The same bacteria also causes finrot, but you are far beyond the finrot stage.

It is normally caused by poor water conditions when Aeromonas takes over and causes internal bacterial infection.

You will have to get rid of the majority of this bacteria asap, or else you may loose all your fish.

Your best bet at this stage is to increase your salt level to 5kg / 1000 liters and proceed with aggressive potassium treatments every second day until you are able to maintain pink water for at least 6 hours. 0.45 g / 1000 liters. (At least four treatments, but possibly five)

Do 30% water changes after each treatment.

See dosages and treatment under the general disease/medication section of the forum.

If that does not help, you have to consider Baytril injections on the valuable fish, because you clearly have an advanced case of infection.

I will have to agree with Paul concerning the Potassiam Treatments because potassium kills off everything.....

Thanx for the help.

Panorama Petshop could not help me with Potassium, but got it at the chemist.Hercules Potassium Permanganate BP - 25g holder.

Not sure what Paul would suggest but i usually use 3g per 1000L. Remember to also buy hydrogen peroxide at 20 ml per 1000 litres. Rather buy more hydrogen peroxide than what you need just incase you make your potassium to strong.

Try to maintain the treatment for at least 6-8 hours. Watch your fish for signs of severe stress. It is normal for them to look unhappy, breath a little fast and appear somewhat listless while under treatment. They should still react if you approach the pond. If they do not move when approuched, wave your had over them. If they still do not move, it means it is time to end the treatment.

IF you can't keep the water pink for 6-8 hours you can add another 1.5 grams of potassium per 1000 litres pond water.

When you decide to end the treatment, add Hydrogen Peroxide 20% at a rate of 20 ml per 1000 litres of pond water. The water will start to clear within about 10 minutes.

Dechlorinator or hydrogen peroxide in the water will inactivate the treatment (for 2 to 3 days).

REMEMBER!!! ALL UV LIGHTS TO BE TURNED OFF DURING ANY TREATMENT

Maybe in general,

How does a thing like this starts and how to prevent it? I saw somewhere people talking about heating the water in the winter.

As Eugen said, from any chemist. Most Koi medications can be bought at a any checmist and mixed by one self, all you need is the list of ingredients and the quantities. And it works out way cheaper.

Anyone have so advice on Algae Blocks?

A friend reccomended it - he is using it in his pond, water stays clean without any UV Light!

Thanx again to all the people with the help so far.

Hi Abri

I meant to say 0.45 of a teaspoon which equals 2.65 grams. A standard teaspoon if flattened = 6 grams. (Basically the 3 grams/half a teaspoon suggested by Wayne) See my post on dosages of standard medication under general diseases. I am very sorry.

Thanks for rectifying this Wayne. My mind must have been somewhere else. Embarassed

Abri, I would not bother with algae blocks, especially after your Potassium treatment. It will sort out your algae and winter lies ahead.

OK,

Will do so.

I did my 1st treatment yesterday and maybe my mind is playing tricks on me, but it looks like the wounds on the sick fish have a blue/purple colour as if the medicine sticked on it.

Will keep you posted.

Thanx

Very Happy

Further to your question what the cause might be, it is normally caused by poor water conditions, especially lack of oxygen or areas in the pond where there are no circulation, for instance behind plants. It is also caused by overstocking or an introduction of an infected fish.

Due to load shedding numerous ponds were infected, because the Aeromonas multiplies in the sand filters during the power cuts, and when the power goes on again, all those bad bacteria are being pumped into the pond, infecting the fish. That is why you should try to backwash your filters when the power goes on again, before it resumes with normal filtration.
