LOL.

Koi don't mind being in the same pond as those giant gold fish ?

Do they eat koi food too ?

Wayne, jy moet oppas, die asyn sal die PH opjaag:lol!:

One of my fish started to look distressed and I added 90g of Potassium Permanganate to my pond (30000L but maybe slightly larger due to flower pond and other variables)
Water stayed pink after 2 hours and fish did not jump or looked uncomfortable, then my girlfriend went to sleep since it was cold in Bloem and about 11pm

My question is what amount of Hydrogen Peroxide and what strength should be added when?
If you search the internet they come up with 0.3%, 5% and 40% and the amount is unclear. I have a 40% solution (500ml)This stuff is potent and will even remove your skin, so do I need to add the HP at all, or under what conditions?
Will it not be better to use a weaker solution? 40% seems a bit strong and to dilute it will be a nightmare

1 Do I need to turn the UV's off during treatment?
2 Is 4 treatment 2 days apart the correct prosedure?
3 20% water replacement after every treatment?
4 HP only to be added if water stays pink after 6hours?
5 Do I need to add HP when I finish the treatment or only a
water replacement?
6 Is it wise to use 75ml of 40% HP or should I rather return it
and get 750ml of 3% HP

Try not to use HP where possible. It is bad for water quality. I also use to use it until i found out that its apparently bad for water quality.

When the water goes orangy - that is a sign that the PP is working out.

I keep HP handy just incase for emergencies but try not to use it. Keep the UV off during treatments.

I terminate my treatments with the use of the UV.

Thanks Wayne

The water was light brown this morning. Does that mean I must add PP again, or should I wait 2days and replace some water and then add PP again?
Is 4 treatments recommended, and should I then add Bio booster to get the filter system back to normal faster?
I did not bypass the 4000L filter as I believe I need to get rid of all the baddies in the pond.

I will recommend waiting 2-3 days between treatments. Keep in mind that PP can damage the gills of the koi.

I also have/had a bacterial problem in my pond and have resorted to PP. I have done 8 treatments of PP.

The first 5 was done 2 days apart and the other 3 treatments was done 7 days apart but i waited 2 weeks between the first 5 treatments and the other 3. So far it looks like i am winning the battle.

After the PP treatment you can do a 10%-20% water change for everyday for 2 days ...thats what i do.

I have also unpacked all my filters and media including the oyster shells and then i PP'd it all sepeartely with strong dose. In other words i am going to have a virgin pond.

I have also cut back the feeding to twice a week as my filter is ofcourse not up and running yet. The best way to boost the filter that i know of is with Bao Bio Clear.

I also feed pellets with olive oil , garlic and lots of honey to try and boost the imune system o the koi.

My koi that have been affected are in qt with .06% salt and methelyne blue anti-bacterial. Almost all of them have recovered. I must add that i PP dipped each one individually before going into the qt and dipped them 3 times afterwards - weekly. 1g PP for 10l of water. For 5 minutes. I really think this played a big role as the koi in the qt recovered while some in the main pond was still being affected by the bacteria while i was doing the PP treatments on the pond.
