Het enige iemand hier ondervinding met Virkon S?

Ek weet mens kry Virkon S 200g (R 30.00) en Virkon S Aquatic (R 990.00). Virkon S Aquatic werk blykbaar beter in 'n koi dam maar ek nie suke geld om in die water tegooi nie ...Ek het vandag die normale Virkon S gekoop. Ek weet mens kan dit in 'n koi dam gebruik en soek net asseblief die formule hoe om dit temeng en die beste maniere om dit tegebruik van week na week. Ek skat mens moet die UV soos gewoonlik afsit maar vir hoe lank?

Vir die wat nie weet wat Virkon S is nie.
Quote:
Virkon S is a broad spectrum disinfectant that is effective against viruses, bacteria and fungi.

Effective against Koi Herpes Virus and all major virus families affecting fish. Works at low temperatures with proven efficacy against key fish pathogens.


Ek wil dit gebruik net om my algehele toestand van my koi en koi dam te verbeter. Ek sal enige additionele informasie waardeer.

Wayne

Hi Wayne

As our farm was most probably the first in SA to be disinfected with Virkon S five years ago we should know the formula.

Pond Treatment 5g/1000L and repeat it after 5 days no need for water changes. Safe to use with salt at 0.3% or 3kg/1000l. No UV lights must be working.

For disinfecting ponds with out koi in it 25g/1000l once off run system for 24 hours with the Virkon S in the water. Empty the system and rinse with clean water. Full system with clean water and follow protocols of a new pond.

So do i leave the UV off the whole time? Is the water not going to turn green? Do you have to do it every 5 days or can i add it say; only once a month?

Enige idee waar 'n mens Virkon S Aquatic in Suid Afrika kan kry teen 'n redelike prys?

Virkon S Aquatic kos maar $25 op die NET maar binnelands verkoop Cape Koi dit vir R 990.00, hulle voer dit in en ek weet van geen ander plek waar mens die Aquatic weergawe kan kry nie.

I do not have personal experience of Virkon. Being also a dealer, I believe that my Koi should not be raised in a setup that is too sterilized. If the fish are not exposed to various bacteria, the fish don't build up an immunity against various bacteria. So, if I sell fish, they should be able to handle the bacteria present in my client's pond.

I rather sell fish with an high immunity and believe that the constant or regular use of Ozone, Virkon and other products that make you pond more sterile, will lesson the immunity of the fish.

The principle is the same with frequent use of Potassium Permanganate which actually does more or less the same as Virkon S. (Virkon S is Potassium Peroxomonosulph.)

If you don't ever expose your children to bacteria by cleaning the house with anti-bacteria everyday, they get sick so much easier when exposed.

Based on hearsay, Virkom will affect your Bio filter only if you overdose, but because your filter don't have to work as hard as in systems without Virkon, it will obviously influence the effectiveness of the filter over time. The effectiveness of filters change in accordance with the need. That is why you should always add new fish gradually, to give the filter time to adapt to the new load of fish waste.

Should you stop the addition of Virkon, you might get spikes of Ammonia and Nitrites and possible bacterial infection.

If you start to use at on a regular basis, you should continue.

As an alternative to Potassium Permanganate in the event of a bacterial problems, I believe it is an option.

For initial sterilization in a new setup or after serious health problems or new begin, I heard that it is great.

Please share your experiences.

So far i don't have much experience with it, but i agree with you. It can't be a good thing to add it every week.

Something that i can mention is that once the virkon S was added, foam started to appear everywhere where the water got agitated. Yesterday the foam was 5cm thick and almost covered my whole pond...after 20 minutes all the foam disappeared...And i only added 3g /1000L yesterday - i added the rest of the 5g / 1000L today.

I have been having a few health issues with my koi in the last 4 weeks. In the last for weeks:

1. I lost of ogon that was bleeding from the gills.
2. A 30CM Doits showa developed sores, almost like small ulcers on the head - it recovered by itself.
3. A 56cm Kohaku developed sores on it head...after 3 injections of baytril it looks much better.
4. A 35cm Torazo Kohaku (Stunning fish) seems like it is developing Popeye...It has not turned into dropsy yet.

As you can see i have a few health issues going on at the momment, no new fish was added since Nov 2007, and i am not sure where the problem is coming from. The water parameters are all perfect.

I have already decreased the koi stocking densities to 1 koi / 2133L and my pond does automatic water changes of 400L a day. So now i have resorted to Virkon S. I plan to do a series of weekly treatments on my pond for the next 4 weeks.

The only bad thing that happened to my pond before all these issues is that some cement fell into the water when the cladding was put on my pond.

It doesn't sound very good and you have my sympathy.

Before I read your last sentence, I thought of asking you about the cement, because I saw how cloudy your pond was when you posted the photo of your pond a while back. (Other possible poisonous substances in the grouting?)

Your koi was clearly exposed to quite a lot of stress lately due to the fairly new environment(new bigger pond), all the noise while building, and surely you moved the koi to a temporary pond at one stage.

I have seen major problems with Koi ponds after cement fell in the water. Apart from the fact that wet Cement is poisonous, it also tend to create PH crashes due to the alkaline content.

Although you have a very good top of the range filtration system, your pond is not mature yet, which also must have contributed to unnecessary stress.

You also have a leak. If water levels dip frequently, I found that the fish gets stressed out. They probably think, "O boy, we are going to run out of water." :-)

As you probably know, stress is one of the major contributing factors of a bacterial infection. It breaks down the immune system of the fish, and the Aeromonas takes over. (Pop eye often indicates that Aeromonas is present, esecially if all the fish has the same symptoms)

The problem with Aeromonas, if it already infected internally, Virkon might not do the trick, as it is only effective against external bacterial problems. However, it will bring down your bacterial count and prevent further internal infection (if any)

You said that the Baytril worked for the Kohaku. That means that Baytril is effective against this particular culprit in your pond. I would consider Baytril injections on all the sick looking fish if they deteriorate further.

If you see an improvement, stop treating and don't go the Baytril route and maintain very high salt levels and very frequent water changes.

(Instead of Virkon, I personally would rather use Acraflavine, Potassium Permanganate, or even Chloramine T to get the bacterial count down. I see Virkon rather as a preventative treatment)

I used plain cement and sand.

Very true, moved from the big pond to a small pond 2500L with 17 fish in it!! Then moved back to the main pond. The cement fell into the water - it took a week to clear up. Then i had to net a the big kohaku to treat it with baytril.

This is true and not true...My main bio filtration (400L Kaldness) is now 1 year old already..i fed the filters twice a day with ammonia to keep it alive while i worked on the pond...ofcourse all the other equipment is new and the pond itself can be classified as new.

Thanks for the advice, i think i will do this.

At the momment my pond water is crystal clear and all the water parameters are where they are ment to be.

As i said before, i get lots of foam when doing the Virkon S treatment which is strange...i have asked around and it is not suppose to do that. So i wonder if it is reacting to something in my water!? Remember i had a simular problem with foam after a patasium treatment about a month or two ago.

Wayne,
Foaming after Virkon S is normal.
It looks and smells like soap.
I only treat at 2g / ton of water.

Hi Wayne

Sorry I was away for a week.

Virkon S is Potassium Peroxomonosulph so it will foam up but the foam will go away after a period.

Yes, keep the UV off for the 10 days. After 10 days the UV's will clear the water fast.

Only do 2 treatments if you need to use Virkon S.

You could treat with Virkon S every 3 - 6 months or after Shows or during QT or after adding new koi to your pond.

You could bay it from Du Pond Lab’s they are the manufacturers of it.

Thanks Colin, I discovered the local depont branch about three days ago.

They told me that they are waiting for Virkon S Aquatics to be registered...so that they can sell it locally. Apparently they have been waiting for 1 year already but there is a lot of red tape and they expect to wait another year.

Differences between Virkon S and Virkons S Aquatics according to Jolanda from Dupont.

Virkon S..................Virkon S Aquatics
Powder........................Tablets
Contains colourant.......Contains no colourants
Contains fragrance.......Contrains no fragrances
..................................Contains anti-foaming agent.

A guy called Wouter from dupont gave me some inside info...Click on the spoiler below to see.

Spoiler:
Virkon S Aquatics are being sold without a label at the momment in Cape town for R 400 / 5 Kg...he gave me the details

Paul, i see that you recommend PP for treating Aeromonas bacteria but dont you think Virkon S is a better or an easier solution for the job?

Its anti-viral, anti-bacterial and ant-fungal plus you don't have to keep an eye on the pond for 6-8 hours during treatment, plus the treatment lasts 10 days....just makes life a bit easier.

See this URL for all the things that it can treat. http://www2.dupont.com/DAHS_EMEA/en_GB/ahb/fish/efficacy_data.html
